Answer:
B. 5 + 2(3+2x) = x + 3(x+1)
Step-by-step explanation:
5 + 2(3+2x) = x + 3(x+1)
5 + 6 + 4x = x + 3x + 3
11 + 4x = 4x + 3
4x - 4x = 3 - 11
0 = - 8, which is absurd.
Hence the equation 5 + 2(3+2x) = x + 3(x+1) has no solution.

- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set up equation</u>
(8x + 2) + 70 + 60 = 180
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 8x + 132 = 180
- Isolate <em>x</em> term: 8x = 48
- Isolate <em>x</em>: x = 6
