Westkost [7]

Answer:

  • 18 ft and 30 ft

Step-by-step explanation:

<u>The new dimensions will be:</u>

  • 10 + x and 22 + x

The area is 540

<u>Using area equation we get:</u>

  • (10 + x)(22 + x) = 540
  • x² + 32x + 220 = 540
  • x² + 32x = 320
  • x² + 2x*16 + 256 = 320 + 256
  • (x + 16)² = 576
  • x + 16 = √576  (Ignoring the negative root as the length is never negative)
  • x + 16 = 24
  • x = 8

<u>The new dimensions are:</u>

  • 10 + 8 = 18 ft and
  • 22 + 8 = 30 ft

Which two equations would be most appropriately solved by using the zero product property?

For the zero product property questions it's choices 2 and 3 since they're quadratics factored and set equal to zero.

for the quadratic formula questions it would be answer choices 2 and 3 also because they're unfactored trinomial quadratic expressions
