Step-by-step explanation: Snap Add?
I don't know what this means:
"because the consecutive angles of a parallelogram are . Solving for x gives x ="
I know that (5x-12) + (x+6)
1. 5x-12+x+6=0
2.6x-6=0
3.6x=6
4.x=1
Answer:
-243
Step-by-step explanation:

Answer:
(3x-1)(2x+1)
Step-by-step explanation:
1-6x^2-x=0
-6x^2-x+1=0
6x^2+x-1=0
6x^2+(3-2)x-1=0
6x^2+3x-2x-1=0
3x(2x+1)-1(2x+1)=0
(3x-1)(2x+1)=0
So the factor is (3x-1)(2x+1)
X equals 60 degrees (80-20=60)
