First we need to find the distance from G to A, or the length of segment GA
For now we'll call this x since it's unknown. This value x adds to the other three sides of the figure to get the perimeter to be 172 inches (given)
So,
EG + GA + AM + ME = perimeter
56 + x + 56 + 35 = 172
x+147 = 172
x+147-147 = 172-147 .... subtract 147 from both sides
x = 25
So segment GA is 25 inches
We'll use this to find the length of segment G'A' which corresponds to GA
The other horizontal sides EM and E'M' also correspond, so we'll pair these sides up and form the proportion below
(GA)/(G'A') = (EM)/(E'M')
which turns into this
25/y = 35/14
when we use y in place of G'A'. Like x, y is unknown at first until we solve for it. Let's isolate y
25/y = 35/14
25*14 = y*35 .... cross multiply
350 = 35y
35y = 350
35y/35 = 350/35 .... divide both sides by 35
y = 10

<h3>Final Answer: The length of G'A' is 10 inches</h3>
Answer:
2x/(x+3) +3/(x-3) = 8/(x^2
[2x(x-3) +3(x+3)]\( x^2 - 9) =8/(x^2 -9)
2x^2 -6x +3x +9=8 (x^2 -9) /(x^2 -9)
2 x^2 -3x +9 -8=0
2 x^2 -3x +1 =0
2x^2 -2x -1x +1 =0
2x(x-1) -1(x-1)=0
(x-1)(2x-1)=0
either, or, 2x-1=0
x-1 =0 2x =1
x =1 x= 1/2
hence, x= 1, 1/2
7. 65 + 75 = 140
180 - 140 = 40
( I think this is the answer)
Answer:
A. No, because not all of the pairs represent the same ratio
