Answer:
(x + 3)(x - 5)
Step-by-step explanation:
Well to factor x^2-2x-15,
we need to find 2 numbers that multiply to get -15 and add to get -2.
3*-5 = -15
3x + -5x = -2x
x*x = x^2
Factored (x + 3)(x - 5)

Answer:
13
Step-by-step explanation:
144 = pie radio square
144 divided by pie = 45.83662361
45.83662361 square root = 6.770275003
6.770275003 multiply by 2 = 13.54055001
13.54055001 = diameter
Nicky's plan can be made into this equation y=25+0.15x
Mickey's plan can be made into this equation y=40+0.10x
to make y equal you have to solve out 25+0.15x=40+0.10x you can solve this further into .05x=15 and then into x=300.
