Answer:
this is the correct graph
Answer:
D. 15
Step-by-step explanation:
3x-10=2x+5
to solve subtract 2x from both sides
(3x - 2x) - 10 = 2x + 5 - 2x
add 10 to both sides
x -10 + 10 = 5 + 10
x = 15
The perimeter is the sum of the side-lengths, which we're given! We don't know the value of a, but we can find the perimeter in terms of a by adding up the side-lengths:
So our answer is
.
