Therefore, the value of 2n - 2 is 4.
To fond the area need to be grassed, find the area of the yard and subtract the area of the pool/patio.
(3x - 5)(4x - 10) =
12x^2 - 30x - 20x + 50 = 12x^2 - 50x + 50 Area of yard
(x + 8)(x - 2) =
x^2 - 2x + 8x - 16 = x^2 + 6x - 16 Area of pool/patio
12x^2 - 50x + 50
- ( x^2 + 6x - 16)
---------------------------
11x^2 - 56x + 66 ft^2 LETTER D
