Answer:
Step-by-step explanation:
<u>Given</u>
- The dimensions of the lot are (6+x) feet and (6−x) feet
- The dimensions of the house to be (2+x) feet and (2−x) feet
Area of the yard = Area of the lot - Area of the house
<u>Area of the yard:</u>
- (6 + x)(6 - x) - (2 + x)(2 - x) =
- 36 - x² - 4 + x² =
- 32 square feet
<u>If the house is extended, then the area of the yard will change as:</u>
- (6 + x)(6 - x) - (4 + x)(4 - x) =
- 36 - x² - 16 + x² =
- 20 square feet
Answer:
x - 3 =
square both sides to get rid of square root
x^2 -6x + 9 = 4x - 7 , but remember 4x - 7 can't be less than 0 since it was square roots can't be less than 0
simplify the equation
x^2 - 10x + 16= 0
x = 8, x= 2
but x cannot equal 2, because if we plug in 2, the square root will be negative,
so x can only equal 8
so B is correct.
