Answer: 
, where x= width of the rectangle ( in inches).
Step-by-step explanation:
Let x= width of the rectangle ( in inches).
Then its length = 2x-7 ( in inches).
Area of rectangle = Length × width
= (2x-7) × (x)
= 2x × x -7 ×x
= 2x²-7x
The area of the rectangle is 72 square inches.
Hence, the equation that represents the given situation :
50 x 0.4 = $20
$50 - $20 = $30
Ratcliff
$40 x 0.3 = $12
$40 -$12 = $28
Although, Clothes R Us discount is larger, Ratcliff has the better deal because the sneaker cost $28 vs clothes r us $30.
Answer:
Average rate of change = 0
Step-by-step explanation:
f(z) = -2z^2 - 12z - 19
a = -4 and b = -2
[f(b) - f(a)] / (b-a)
[-2(-2)^2 - 12(-2) -19] - [-2(-4)^2-12(-4)-19] / (-2 -(-4))
(-8+24-19) - (-32+48-19) / 2
(-8+24-19+32-48+19) / 2 = 0/2
