Answer:
3 + 5i
Step-by-step explanation:
Given
- 2i + (9 - 3i) - (6 - 10i) ← distribute parenthesis
= - 2i + 9 - 3i - 6 + 10i ← collect like terms
= 3 + 5i
8 feet x 10 = 80 feet of pipes. 80 x 12 = 960 inches of pipes.
960 inches of pipes / 18 inch piece = 53 and 6/18 = 53 and 1/3
You can get 53 pieces at 18 inches apiece with 6 inches of pipe left over.
