Step-by-step explanation:42 is the angle of A and C together so it is the same on the other side
Answer:

Step-by-step explanation:
50 * 5x = 5000
Dividing both sides by 50
=> 5x = 5000/50
=> 5x = 100
Dividing both sides by 5
=> x = 20
Add like terms
-4x+x=-3x
6-2=4
So the simplified term is 4-3x
The answer is: -3^2+8(-3)-7=-40
