2/3(6x+3)
2/3 x 3(2x+1)
2(2x+1)
4x+2
Therefore your answer is 4x+2
The point-slope form:

We have the point (4, -6) and the slope m = 3/5. Substitute:

Answer:
20 degree
Step-by-step explanation:
x + x + 70 = 110 degree (sum of two opposite interior angle equal to the exterior angle formed)
2x = 110 - 70
x = 40/2
x = 20 degree
V = π r² h
V = π (4)² 8
V = 402.12
