Answer:
19y-9
Step-by-step explanation:
apply distributive property
-3(-4y)-3 x 3 + 7y
12y - 3 x 3 + 7y
12y - 9 + 7y
add 12y to 7y
19y-9

Answer:
<h2>x = 7</h2>
Step-by-step explanation:
ΔKLJ and ΔNPM are similar (Angle-Angle). Therefore the sides are in proportion:

We have:
MP = 4x - 4
JL = 20
MN = 30
JK = 25
Substitute:
<em>cross multiply</em>
<em>use distributive property</em>

<em>add 100 to both sides</em>
<em>divide both sides by 100</em>
