Answer: triangle F
Step-by-step explanation:
X/(x+2) = (x+2)/(x+5)
(x+2)^2 = x(x+5)
x^2 + 4x + 4 = x^2 + 5x
x = 4
Answer:
1,020
Step-by-step explanation:
That is correct you have it right so I think you're good
So we first minus 6 both sides
7x^2-14x=-6
then we have
A(x^2-2x)=-6
what is A?
hmm (this should be painfully obvous, but if not, here are steps)
7x^2-14x=-6
A(x^2-2x)=-6
7x^2-14x=-6=A(x^2-2x)
7x^2-14x=A(x^2-2x)
undistribute 7
7(x^2-2x)=A(x^2-2x)
divide both sides by (x^2-2x)
7=A
A=7
