Equation at the end of step 1
(3x2 - 38x) + 24 = 0
STEP2:Trying to factor by splitting the middle term
2.1 Factoring 3x2-38x+24
The first term is, 3x2 its coefficient is 3 .
The middle term is, -38x its coefficient is -38 .
The last term, "the constant", is +24
Step-1 : Multiply the coefficient of the first term by the constant 3 • 24 = 72
Step-2 : Find two factors of 72 whose sum equals the coefficient of the middle term, which is -38 .
-72 + -1 = -73 -36 + -2 = -38 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -36 and -2
3x2 - 36x - 2x - 24
Step-4 : Add up the first 2 terms, pulling out like factors :
3x • (x-12)
Add up the last 2 terms, pulling out common factors :
2 • (x-12)
Step-5 : Add up the four terms of step 4 :
(3x-2) • (x-12)
Which is the desired factorization
Equation at the end of step2:
(x - 12) • (3x - 2) = 0
STEP3:Theory - Roots of a product
3.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation:
3.2 Solve : x-12 = 0
Add 12 to both sides of the equation :
x = 12
Solving a Single Variable Equation:
Step-by-step explanation:
[tex]if \: (x + 12) = (3x + 2) \\ 12 - 2 = 3x - x \\ 2x = 10 \\ x = 5 \\ \\ \\ if(x + 12)(3x + 2) = 0 \\ x + 12 = 0 \: \: \: or \: \: \: 3x + 2 = 0 \\ x = - 12 \: \: \: or \: \: \: x = - \frac{2}{3} [/tex]

Rafael can choose plan a or Plan B for his long-distance charges. For each plan, cost (in dollars) depends on minutes used (Per month) as shown below.
Answer:
a. Plan B; $4
b. 160 mins; Plan B
Step-by-step explanation:
a. Cost of Plan A for 80 minutes:
Find 80 on the x axis, and trave it up to to intercept the blue line (for Plan A). Check the y axis to see the value of y at this point. Thus:
f(80) = 8
This means Plan A will cost $8 for Rafael to 80 mins of long distance call per month.
Also, find the cost per month for 80 mins for Plan B. Use the same procedure as used in finding cost for plan A.
Plan B will cost $12.
Therefore, Plan B cost more.
Plan B cost $4 more than Plan A ($12 - $8 = $4)
b. Number of minutes that the two will cost the same is the number of minutes at the point where the two lines intercept = 160 minutes.
At 160 minutes, they both cost $16
The plan that will cost less if the time spent exceeds 160 minutes is Plan B.
This equation shows how the total amount of paper Addison's office has recycled depends on the number of weeks since they started the new recycling plan.
p = w + 16
The variable w represents the number of weeks the office has been on the new recycling plan, and the variable p represents the total kilograms of paper recycled. How many weeks will it take Addison's office to recycle a total of 19 kilograms of paper?

How do I solve 6(5 - 2x) + 12 = -66?
Answer:
x = 9
Step-by-step explanation:
Step 1: Write equation
6(5 - 2x) + 12 = -66
Step 2: Solve for x
Distribute 6: 30 - 12x + 12 = -66Combine like terms: 42 - 12x = -66Subtract 42 on both sides: -12x = -108Divide both sides by -12: x = 9Step 3: Check
Plug in x to verify it's a solution.
6(5 - 2(9)) + 12 = -66
6(5 - 18) + 12 = -66
6(-13) + 12 = -66
-78 + 12 = -66
-66 = -66

$125

$50
deposit
$35
withdrawal -$70
withdrawal -$50
Answer:
5
Step-by-step explanation:
The account balance after transactions will be $90.
What is Addition?
A process of combining two or more numbers is called addition.
Given that;
The account started with a balance of $125 and
deposit $50,
deposit $35
withdrawal -$70
withdrawal -$50
Now,
Deposit in account means to add the amount and withdrawal means to remove money from account.
Since, The account started with a balance of $125.
After deposit $50,
The account balance = $125 + $50 = $175
Again after deposit $35;
The account balance = $175 + $35 = $210
After withdrawal -$70;
The account balance = $210 - $70 = $140
Again after withdrawal -$50;
The account balance = $140 - $50 = $90
Thus, The account balance after transactions will be $90.

Below is a diagram of Hillcrest High School. The english and math buildings are congruent rectangles. The art building is a square. The total perimeter of Hillcrest High school’s building is 1,718 feet. Find the value of x. Find the missing perimeters for the buildings.
1. Find the value of x.
2. Find the missing perimeters for the buildings.
3. What is the area of the English building? (plug in your x value!)
Answer/Step-by-step explanation:
1. Perimeter of the building = sum of all the length of the outer borders surrounding the building = 1,718 ft
Thus:
4x - 6 + 2x + 3x + 2(3x + 4) + 3x + 2x + x + x + x + 2x + 4x - 6 + 2(3x + 4) + 4x - 6 + 3x = 1,718
Open the Parentheses
4x - 6 + 2x + 3x + 6x + 8 + 3x + 2x + x + x + x + 2x + 4x - 6 + 6x + 8 + 4x - 6 + 3x = 1,718
Combine like terms
42x - 2 = 1,718
42x = 1,718 + 2
42x = 1,720
x ≈ 41
2. Missing perimeter of Building = 2x + 2x + 4x - 6
Simplify
= 8x - 6
Plug in the value of x
= 8(41) - 6
= 322 ft
3. Area of English Building = length * width
= (4x - 6 + 2x)(3x)
Simplify
= (6x - 6)(3x)
Plug in the value of x
= (6(41) - 6)(3(41))
= (246 - 6)(123)
= (240)(123)
= 29,520 ft²

Research in March 2019 suggests that 40% of U.S. Adults approve of way President Trump is running the country. We randomly sample 50 U.S. Adults and find that 35% approve of way President Trump is running the country. What is the probability that a random sample of 50 U.S. Adults has less than 35% with this opinion? (Round standard error to 2 decimal places before calculating Z. Round Z to 2 decimal places before using the Normal Distribution Calculator.) Group of answer choices about 0.24 about 0.76 about 0.48
Answer:
The probability is [tex]P( \^ p < 0.35)= 0.2388 [/tex]
Step-by-step explanation:
From the question we are told that
The population proportion is p = 0.40
The sample size is n = 50
Generally the standard error is mathematically represented as
[tex]\sigma_{\= p} = \sqrt{\frac{p * (1- p)}{n} }[/tex]
=> [tex]\sigma_{\= p} = \sqrt{\frac{0.40 * (1- 0.40)}{50} }[/tex]
=> [tex]\sigma_{\= p} = 0.07[/tex]
Generally the probability that a random sample of 50 U.S. Adults has less than 35% with this opinion is mathematically represented as
[tex]P( \^ p < 0.35) = P(\frac{\^ p - p}{\sigma_{\= p}} < \frac{0.35 - 0.40}{0.07} )[/tex]
Generally [tex]\frac{\^ p - p}{\sigma_{\= p}} = Z (The \ standardized \ value\ of \ \^ p )[/tex]
=> [tex]P( \^ p < 0.35)=P(Z < -0.71)[/tex]
From the z table
[tex]P(Z < -0.71) = 0.2388[/tex]
So
[tex]P( \^ p < 0.35)= 0.2388 [/tex]

3) The height of an object that is thrown straight up from a height of 6 feet
above ground is given by h(t) = -15t2 + 25t + 6, where t is the time in
seconds after the object is thrown. Find the average rate of the object from
1 to 4 seconds.
Answer:
- 44 feets
Step-by-step explanation:
Given the model:
h(t) = -15t2 + 25t + 6
Average height of object from 1 - 4 seconds
At :
t = 1
h(1) = -15(1)^2 + 25(1) + 6 = 16 feets
t = 2
h(2) = -15(2)^2 + 25(2) + 6 = - 4 feets
t = 3
h(3) = -15(3)^2 + 25(3) + 6 = - 54 feets
t = 4
h(4) = -15(4)^2 + 25(4) + 6 = -134 feets
Average height:
(16 + (-4) + (-54) + (-134)) / 4 feets = (- 176 / 4) feets
= - 44 feets
