Question 896860: Given the perimeter P, find the missing measurement.
*The picture is showing a triangle*
One side of the triangle has a ? (because it wants you to find it), Another side has 3(x + 2) and the last side has 5x + 3. The perimeter of the triangle is P = 10x + 8.

A perimeter is a fence around.
A + B + C = 10x+8 (the given perimeter)
B = 3(x+2) (given) - distribute, B = 3x+6
C = 5x + 3 (given)
B+C = 8x + 9
A + B+C= 10x+8
Therefore A =
(10x+8)-(8x+9) = 2x-1
Now you have your three sides:
2x-1
3x+6
5x+3
Add them together to get the perimeter

Use a variable for the "One side has a", maybe like q.

You have q%2B3%28x%2B2%29%2B5x%2B3=10x%2B8.
All you can do is solve for q and it may be in terms of x.

q=10x%2B8-3x-6-5x-3
highlight%28q=2x-1%29
