Answer:
x =3.375
Step-by-step explanation:
We can use proportions to solve this problem. Put the smaller triangle side length over the larger triangle side length.
6+x 12
---------- = -----------
25 32
(6+x) *32 = 12*25
Distribute
192 +32x = 300
Subtract 192 from each side
192-192 +32x = 300-192
32x =108
Divide by 32
32x/32 = 108/32
x =3.375
Step-by-step explanation:
multiply both sides by 4,
3x+1=-2x-12
5x+1=-12
5x=-11
x=-11/5
