Answer:
True.
Step-by-step explanation:
The sides are legs and that's what makes it isosceles.
x²+6x²=7x²
then the rest is done for you
7x²+12x+8
5*2x|x|-6=24
10*|x|-6=24
10*|x|=30
Divided both sides of the equation by 10
|x|=3
X=3 X=-3
Hey there!
To figure out what "x" means, you can divide the numbers 126 and 14 . . .
126 divided by 14 = 9
9 x 14 = 126
9 = x
----------------
x = 9

Hope this helps you.
