Answer:
ab + b²-ac-bc
b(a+b) -c(a+b)
(a+b) (b-c)
Step-by-step explanation:
C. (b-c)(a+b)
This i s because there is a positive b squared in the expanded equation so both brackets had to have had a positive b term in them.

The break even point is when the cost equals the revenue.
C=R
15x+150=45x
150=30x
x=5
Plug this back into the original equations to get the y value.
15*5+150=225
or 45*5=225
Answer: it is -1
5*5x=25x
5*3=15
25x+15=-10
25x= -10-15
25x= -25
X=-25/25
= -1
