E(x) = A(x) - S(x) = 2400x + 40x^2 - (250x + 500) = 2400x + 40x^2 - 250x - 500 = 40x^2 + 2150x - 500
Ashton's expenses for 3 years E(3) = 40(3)^2 + 2150(3) - 500 = 40(9) + 6450 - 500 = 360 + 5950 = $6,310
Answer:
So you have it right. 15 5/7 in
Step-by-step explanation:
C = πd
All you can do now is substitute what has been given
Diameter = 5
Pi = 
C = * 5
Multiply from across
22 * 5 = 110 ( numerator)
7 * 1 = 7 (denominator)
110/7 (improper fraction) = 15.71428571428571 ( as a decimal) = 15 5/7 ( as a mixed number)
Ik its 15 5/7 because 1. the 15 wont change, and 2 5/7 = 0.7142857142857143, which is the same one as above
Hope this helped!

The error Alex made is that he found the perimeter of the figure instead of the area.
<h3>Area and perimeter of shapes</h3>
Given the expressions
7+(3x 1.4)+5+2+(5x 14)
He used the expression to simplify the grid
The expression simplified shows that Alex added all the measures of the sides of the grid instead of taking the product of the length and width
Note that the operation Alex performed is the perimeter of the figure instead of the area hence the error Alex made is that he found the perimeter of the figure instead of the area.
