The x-intercept of f(x) = (x + 6)(x - 3)
f(x) = 0 → (x + 6)(x - 3) = 0 → x + 6 =0 or x - 3 =0
x = -6 or x = 3
Therefore the x-intercepts are: (-6; 0) and (3; 0)
Your answer is (-6; 0)
10/8 can be simplified to 5/4, which is the same as 1.25 (divide numerator 5 by denominator 4).
So you have x>1.25.
All numbers greater than 1.25 are possible solutions.
11yd is the diameter and circumference is 2πr = 2π(d/2) = πd = 11π yd
5 times 3 times 8 is the correct answer, because it's like finding the volume.<span />
