Answer:
1. 3v^2 - 33v -28
2. -6k^2 + 16k - 49
Step-by-step explanation:
1. (-7 x 6v) + (-7 x 4) + (3v x 1v) + (3v x 3)
-42v-28+3v^2+9v
3v^2 + 9v - 42v -28
3v^2 - 33v -28
2. (-3k x 2k) + (-3k x -3) + (7 x 1k) + (7 x -7)
-6k^2+9k+7k-49
-6k^2 + 16k -49
1. -7(6v+4)+3v(v+3)
-42v-28+3v ²+9v
-33v-28+3v ²
=3v ²-33v-28
2. -3k(2k-3)+7(k-7)
-6k ²+9k+7k-49
= -6k ²+16k-49
