when (2x - 3)^2 is subtracted from 5x^2, what is the result? And how can I show the answer? Thank you x
first expand (2x-3)^2 (2x-3)(2x-3)=(2x-3)(2x)+(2x-3)(-3)=4x²-6x-6x+9=4x²-12x+9
so 5x²-(4x²-12x+9)=5x²-4x²+12x-9=x²+12x-9

Given: diameter = 12 ft
Area = π r²
r = radius. It is 1/2 of the diameter. r = 12 ft / 2 = 6 ft.
Area = 3.14 * (6ft)² A = 3.14 * 36ft² A = 113.04 ft² or 113.0 ft² rounded to the nearest tenth.
