Answer: Factoring using GCF 2x^2+34x+140-- 2(x+7)(x+10)
x^2+4x-77 --> (x-7)(x+11)
Step-by-step explanation: I don't know if these are 100 percent correct, since I'm learning these as well at the moment but I just wanted to help you out.
1) linear pair
2) adjacent
3) adjacent
4) complementary
5) vertical
6) adjacent
7) linear pair
8) vertical
-5+0.5x= 13
Add 5 to both sides
0.5x= 18
Multiply both sides by 2
x= 36
Final answer: x=36
