Answer:
<h2><u><em>
17/12</em></u></h2>
Step-by-step explanation:
x - 3/4 = 2/3
x = 2/3 + 3/4
x = 17/12
----------------
check
17/12 - 3/4 = 2/3
the answer is good
Answer:y= (3/4)x -7/4
Step-by-step explanation:
[y -(-1)]/[x - 1] = [2 -(-1)]/[5 - 1]
[y + 1]/[x - 1] = 3/4
y + 1 = (3/4)x - 3/4
y = (3/4)x - 7/4.
106=x+x+5+x+8
106=3x+13
3x=93
x=31
(the sides are 31, 36, 39 respectively)
You just need to factor a to get

(6x-2)(6x-2) = 36x-12x-12x+4 = 36x+4
