Answer:
x = -1
Step-by-step explanation:
<h2>
first divide 8 by 2, to get 3x-4 =x-6. then, add four on both sides to get 3x = x-6 + 4. to x's and number on different sides, you are now going to subtract 1x from both sides to get 2x = -6 + 4. solve to get 2x = -2. lastly, divide both sides by 2 do get <u>x = -1</u>

Because the triangles are congruent,
all their corresponding sides are equal,
so 2x-9=x+5, x=14
first side : x+5=14+5=19
second side: 15
third side: 8
P = 19+8+15= 42 Answer is D
