Question

Need help with this problem, doesn't make sense to me.

Answer 1

Answer:

A = x² - 5x - 8

Step-by-step explanation:

Finding x

• Area (deck) = Area (Rectangle) - [Area (bench) + Area (planter)]
• A = x(x - 4) - [ 2(6) + 1/2(2)(x - 4) ]
• A = x(x - 4) - [12 + x - 4]
• A = x² - 4x - 8 - x
• A = x² - 5x - 8
