Answer:A triangle has a perimeter of 165 cm. The first side is 65 cm less than twice the second side. The third side is 10 cm less than the second side. Write and solve an equation to find the length of each side of the triangle.
The sides can be found by taking the square root of the area. , where = side. . So the length of a side is 6.3 cm.

Hi, could any one explain how to find the amount of prime numbers between numbers?
Explanation;
A prime number is a positive integer that has exactly two positive integer factors, 1 and itself.
Note that the definition of a prime number doesn't allow 1 to be a prime number:
1 only has one factor, namely 1.
Prime numbers have exactly two factors, not "at most two" or anything like that. When a number has more than two factors it is called a composite number.
Prime Numbers between 1 and 200 are;
{2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199}
So the above listed examples are prime numbers because they have only two factors.
Equation parallel y= -3 also passes through the point (2,5)
Answer:
When somethins is parallel it never crosses each other, this means the new equation has to have the same slope but, since y=-3 is a straight line we just have to make the new line also a straight line, maknig sure it passes through (2,5).
To do this make y equal the y-coordinate of the points it needs to pass through. This would make the answer y=5

[tex]4z + 2 = 10z - 1[/tex]
Add sides 1
[tex]4z + 2 + 1 = 10z - 1 + 1[/tex]
[tex]4z + 3 = 10z[/tex]
Subtract sides 4z
[tex] - 4z + 4z + 3 = - 4z + 10z[/tex]
[tex]3 = 6z[/tex]
[tex]6z = 3[/tex]

Answer:
f(m) = 25-2m
Step-by-step explanation:
Let m be the number of maps Jan buys.
Let f(m) be the amount she has left after buying maps
f(m) = 25-2m
Equation to represent the amount she will have left of she buys maps is
f(m) = 25-2m
What is an equation?"An equation is a mathematical statement that is made up of two expressions connected by an equal signs."
Given
Cost of each map = $2
Total amount Jan have = $25
Let m be the number of maps Jan buys.
Let f(m) be the amount she has left after buying maps
f(m) = 25-2m
Thus, equation to represent the amount she will have left of she buys maps is f(m) = 25-2m.

The Olympic swimmer, Michael Phelps, required 10,000 calories during training. He needed 30% protein, 50% carbohydrates and 20% fat. How many calories did he need for each nutrient?
1 gram of carbs= 4 calories, 1 gram of protein=4 calories, 1 gram of fat= 9 calories.
Answer:
750 grams of protein, 222.22 of fat, and 1,250 of carbs.
Step-by-step explanation:
3,000 calories from protein, 2,000 from fat, and 5,000 from carbs.
3000 / 4 = 750 grams of protein.
2,000 / 9 = 222.22 grams of fat.
5,000 / 4 = 1,250 grams of carbs.

A tree that is 6 feet tall casts a shadow that is 4.5 feet long. If a boy is standing near the tree has a shadow that is 3 feet long, how tall is the boy? Draw a picture and show your work.
=======================================================
Work Shown:
See below for the diagram.
(person height)/(person shadow) = (tree height)/(tree shadow)
x/3 = 6/4.5
x*4.5 = 3*6
4.5x = 18
x = 18/4.5 ...... dividing both sides by 4.5
x = 4
The boy is 4 feet tall.

A company has two manufacturing plants with daily production levels of 5x +14 items and 3x-7 items, respectively. The first plant produces how many more items daily than the second plant?
Answer:
The first plant produces 2x + 21 more items daily than the second plant.
Step-by-step explanation:
The daily production of the two plants are:
Plant 1: 5x + 14
Plant 2: 3x - 7
Compute the number of items first plant produces more than the second plant as follows:
[tex]\text{Plant 1 - Plant 2}=5x+14-3x+7\\\\=2x+21[/tex]
Thus, the first plant produces 2x + 21 more items daily than the second plant.
11) Which of the following is zero of the polynomial x^3+x^2+x+1
1
-1
both options 1 and 2
None
please answer
Answer:
The correct answer is option 2: -1
Step-by-step explanation:
In order to check if a number is zero of a function or not, the numer is put into the function in plave of variable. If the answer is zero thent he number is zero of the function and if the answer is not zero the given number is not a zero of the function.
Given function is:
[tex]x^3+x^2+x+1[/tex]
Putting x=1
[tex]=(1)^3+(1)^2+1+1\\=1+1+1+1\\=4[/tex]
1 is not zero of the function.
Putting x = -1
[tex]=(-1)^3+(-1)^2+(-1)+1\\=-1+1-1+1\\=0[/tex]
-1 is zero of the given function.
Hence,
The correct answer is option 2: -1

Factor the expression x4 − y4 using the polynomial identity (x2 − y2) = (x − y)(x + y). Hint: x4 = (x2)2 and y4 = (y2)2.
Answer:
(x - y)(x + y)(x² + y²)
Step-by-step explanation:
[tex]x^{4}[/tex] - [tex]y^{4}[/tex] ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b), thus
[tex]x^{4}[/tex] - [tex]y^{4}[/tex]
= (x²)² - (y²)²
= (x² - y²)(x² + y²) ← x² - y² is also a difference of squares, then
= (x - y)(x + y)(x² + y²)

helpp plzzzz its really confusing. don't answer jus for points if u don't know it.
Answer:
2. B) n > 2
4. B) -3
5. C) 1[tex]\frac{1}{2}[/tex] (Which is equal to 1.5)
8. D) x > [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
2. -6n < -12
To solve for n, divide by -6. When divide by a negative, you flip the sign.
n > 2
4. 2(n + 5) [tex]\geq[/tex] 4 and 3(n - 1) < 3
Divide by 2 for the first inequality and divide by 3 for the second inequality.
n + 5 [tex]\geq[/tex] 2 and n - 1 < 1
Now subtract 5 and add 1
n [tex]\geq[/tex] -3 and n < 2
Since the inequality says and, both equations have to be true when n is plugged in. We can see that -3 works, since it is equal to -3 AND is less than 2.
5. 4x - 7 [tex]\geq[/tex] [tex]\frac{-12x+14}4}[/tex]
Multiply by 4 to both sides
16x - 28 [tex]\geq[/tex] -12x + 14
Now add 12x and add 28.
28x [tex]\geq[/tex] 42
Divide by 28 to get x.
x [tex]\geq[/tex] 1.5
So the answer is C.
8. 3(2x - 1) > 4x - 2
For this one, distribute the 3 to the numbers in the parentheses.
6x - 3 > 4x - 2
Add 3 and subtract 4x.
2x > 1
Divide by 2.
x > [tex]\frac{1}{2}[/tex]
