This product involves zero. So, you don't have to bother and compute all the factor, because if you multiply anything by zero you get zero.
Answer:
A. x + 9
Step-by-step explanation:
x² + 5x - 36 = (x + 9) (x - 4)
Scale factor = XY/UV = YZ/VW = XZ/WV
Scale factor = 21/3 = 28/4 = 14/2
Scale factor = 7
Answer= X>3
5x>15
Divide both sides by 5x

5x will cancel with 15. You get 3
So, x>3
I think 115 min because its just 23 x 5 so you just multiply that to get the asnwer
