Answer: 300 square feet  

Step-by-step explanation:

length of walkway = 20 + 2x

width of walkway = 15 + 2x

A(x) = (20 + 2x)(15 + 2x)

A(x) = 300 + 30x + 40x + 4x2

A(x) = 300 + 70x + 4x2

Solve and graph the inequality 6.7>-0.2x+4.5 look at picture to get the exact equation and answer choices!
Taya2010 [7]
Let's do it !

(6.7 ≥ -0.2x + 4.5)
↔ (6.7 - 4.5 ≥ -0.2x)
↔ (2.2 ≥ -0.2x)
↔ (2.2/-0.2 ≤ x)
↔ (-11 ≤ x)

In short, the answer would be : D. x ≥ -11.

Hope this helps !
