Answer:
5 inches.
Step-by-step explanation: Take a length from the original (13.5) and divide it by the new length of that side (9) to get 1.5. Then take 7.5 and divide it by 1.5 to get 5 inches.
Is this a circle? We need a picture
The first one
1 because if your see it on the scale it shows -2 and 2 then add that up there you go
Z²(z-1)-9(z-1)
= (z²-9)(z-1)
= (z+3)(z-3)(z-1)
X² - 4x - 12 =
x² + 2x - 6x - 12 =
x(x + 2) - 6(x + 2) =
(x + 2)(x - 6)
