Answer:
what do you mean
Step-by-step explanation:
Answer:
x + 2 + x + 2 + x + 2 + x + 2 + x + 2 + x + 2 + x + 2 + x + 2 + x + 2 = 9x+18
so there are 9 twos or 18 and 9x. No value is provided for x so the answer is 18+9x.

Evaluate the function.
Given f(x) = x2 - 5x + 5, find f(3).
Answer:
f(3) =-1
Step-by-step explanation:
f(x) = x^2 - 5x + 5
Let x=3
f(3) = 3^2 -5(3) +5
= 9 -15+5
= -6+5
=-1
A rectangle has a length 3 times the width. What is the perimeter in terms of x?
Answer:
Perimeter is equal to all four sides added together.
Length = 3W; L=3W
So
P = 2(W) + 2(L) substitute the equation for length above you get
P = 2(W) + 2(3W) and combine
P = 2W + 6W = 8W; put in what the perimeter is and solve for W
66 = 8W, so W = 8.25
W = 8.25, L = 24.75

x-5(x-1) = x- (2x-3)
Answer:
Step-by-step explanation:
x-5(x-1) = x- (2x-3)
x + x *(-5) + (-1) * (-5) = x + 2x*(-1) + (-3)*(-1) {use distributive property}
x - 5x + 5 = x - 2x +3 {Combine like terms}
-4x + 5 = - x +3 {Add 'x' to both sides}
-4x + 5 + x = -x + x + 3
-3x + 5 = 3 {subtract 5 from both sides}
-3x = 3 - 5
-3x = -2 {Divide both sides by (-3)}
x = -2/-3
x = 2/3
The average score in an examination taken by 52 students of a class is 85. If the scores of the best 5 performers are not considered, the average score of the remaining students falls by 2. If, none of the first five highest scorers is not below 80 and if each of the 5 top scorers had distinct integral scores, find the maximum possible score of the topper.
Answer:
177
Step-by-step explanation:
If the top 5 performers are not considered, the average drops by 2.
Thus,average without top 5 performers = 85 - 2 = 83
Total scored with 5 table toppers = 52 × 85 = 4420
Total scored without 5 table toppers = 47 × 83 = 3901
Total scores of top 5 table toppers = 4420 - 3901 = 519
We are told that each of the 5 top scorers had distinct integral scores.
Also, all of them will score greater than 83.
Thus,possible maximum score of table topper = 519 - (84 + 85 + 86 + 87) = 177

Answer:
2) x = -3
Step-by-step explanation:
Collect like terms, so gather all your x's on one side, and numbers in the other. Add -6x and +15 to both sides, so you get -2x - 6x = +9 + 15, so we have -8x = 24, divide both sides by -8 you get x = -3.

Factor by grouping 8y3–4y2–14y+7
Answer:
[tex](2y - 1)( {4y}^{2} - 7)[/tex]
Step-by-step explanation:
1) Factor out common terms in the first two terms, then in the last two terms.
[tex] {4y}^{2} (2y - 1) - 7(2y - 1)[/tex]
2) Factor out the common term 2y - 1.
[tex](2y - 1)( {4y}^{2} - 7)[/tex]
Therefor the answer is, ( 2y - 1 ) ( 4y² - 7 ).
Answer:
[tex] \huge \boxed{ \boxed{ \red{ \sf (4 {y}^{ {2} } - 7)(2x - 1)}}}[/tex]

Answer:
The perimeter of the garden, in meters, is [tex]24\sqrt{2}[/tex]
Step-by-step explanation:
Diagonal of a square:
The diagonal of a square is found applying the Pythagorean Theorem.
The diagonal of the square is the hypothenuse, while we have two sides.
Diagonal of 12m:
This means that [tex]d = 12[/tex], side s. So
[tex]s^2 + s^2 = 12^2[/tex]
[tex]2s^2 = 144[/tex]
[tex]s^2 = \frac{144}{2}[/tex]
[tex]s^2 = 72[/tex]
[tex]s = \sqrt{72}[/tex]
Factoring 72:
Factoring 72 into prime factors, we have that:
72|2
36|2
18|2
9|3
3|3
1
So
[tex]72 = 2^{3}*3^{2}[/tex]
So, in simplest radical form:
[tex]s = \sqrt{72} = \sqrt{2^{3}*3^{2}} = \sqrt{2^3}*\sqrt{3^2} = 2\sqrt{2}*3 = 6\sqrt{2}[/tex]
Perimeter of the garden:
The perimeter of a square with side of s units is given by:
[tex]P = 4s[/tex]
In this question, since [tex]s = 6\sqrt{2}[/tex]
[tex]P = 4s = 4*6\sqrt{2} = 24\sqrt{2}[/tex]
The perimeter of the garden, in meters, is [tex]24\sqrt{2}[/tex]

A triangle has an area of 36 cm². The base and height are scaled by a factor of 5.
What is the area of the resulting triangle?
Enter your answer in the box.
Answer:
900
Step-by-step explanation:
The area of the final triangle would be 900 cm².
What is scale factor?Scale factor is used to compare the final and initial dimensions of the figure. Mathematically, we can write scale factor -
{K} = {final dimensions/initial dimensions}
Given is that a triangle has an area of 36 cm². The base and height are scaled by a factor of 5.
Assume the initial dimensions of the triangle be {x} and {y} respectively. So, we can write the initial area as -
{1/2}{x}{y} = 36
{x}{y} = 72
After the scaling, we can write the final area as -
A = {1/2}{5x}{5y}
A = {25/2}{x}{y}
A = 12.5 x 72
A = 900 cm²
Therefore, the area of the final triangle would be 900 cm².

Write an equation that relates the number of peppers, n, and the
cost, C.
Complete Question:
The local Farm Market sells peppers at five for $2.25. Write an equation that relates the number of peppers, n, and the cost, C.
Answer:
[tex]C = 0.45n[/tex]
Step-by-step explanation:
Given
[tex]5\ peppers = \$2.25[/tex]
Required
Determine the relationship between C and n
[tex]5\ peppers = \$2.25[/tex]
Divide both sides by 5, to get the cost of 1 pepper
[tex]\frac{5\ peppers}{5} = \frac{\$2.25}{5}[/tex]
[tex]1\ pepper = \frac{\$2.25}{5}[/tex]
[tex]1\ pepper = \$0.45[/tex]
Multiply both sides by n to get the cost of n pepper
[tex]n*1\ pepper = \$0.45*n[/tex]
[tex]n\ pepper = \$0.45n[/tex]
So, we have:
[tex]C = 0.45n[/tex]
