Step-by-step explanation:
G(x) =4(2x)-6
G(x)=8x-6
Subtract 350 from both sides then divide both sides by 25.
(c-350)/25 = h
(-1,-4) this is saying that when x=-1, y=-4. Plugging it into the line equation y=4x gives

Which is correct.
Answer is A
The binomial can be factored using the difference of squares formula a2-b2 = (a+b) (a-b) where a=x and b=9
(X+9) x(x-9)
