Answer:
a = 0
Step-by-step explanation:
3(4a+7)=5(2a+4)+1 Distribute 3 through the parentheses
- > 12a + 21 = 5(2a + 4) +1
5(2a + 4) +1 --> 10a + 20 + 1
12a + 21 = 10a + 20 + 1 --> 12a + 21 = 10a + 21 --> 12a = 10a
12a - 10a = 0 --> 2a = 0
Divide both sides of the equation by 2 --> a = 0
The answer will be x=2i,-2i

Answer:
m/_2 = 127°
m/_4 = 127°
m/_1 = 53°
m/_3 = 53°
Step-by-step explanation:
angle 2 and 4 are the same in the diagram.
to get angle 1 and 3 i did:
