Answer:
8x+4
Step-by-step explanation:
4(2x+1)=8x+4
X + 2(x + 4) = 32
3x + 8 = 32
3x = 24
x = 8
The lengths of the sides are 8, 12 and 12 (answer),
3(x + 8) = 17....distribute the 3 thru the parenthesis
3x + 24 = 17...subtract 24 from both sides
3x = 17 - 24
3x = -7...divide both sides by 3
x = -7/3 or -2 1/3 <===
