(x-9)(x+7)=0
x-9=0 or x+7=0
x=9 or x=-7
:)
49 because you multiply 7x7
Answer:
g(f(4)) = -3
Step-by-step explanation:
f(x)=x-7
g(x) = x
g(f(4))
f(4) = 4-7
f(4) = -3
g(-3) = -3
In order for this to be solved we need to know the angle of each side. This question cannot be solved unless you show us the Diagram. I'll be happy to help once that is settled<span />
