Answer:
7x21
Step-by-step explanation:
First, we need to find the length of the pool. Since it is three times as long as it is wide, it is 21 feet long (7 x 3 = 21). That way we can tell that it is 7x21, with a perimeter of 56 feet, and an area of 147 feet squared.
Answer:
m = 4
Step-by-step explanation:
Given
- 8 + 6m =
(4m + 16) ← distribute parenthesis
- 8 + 6m = 2m + 8 ( subtract 2m from both sides )
- 8 + 4m = 8 ( add 8 to both sides )
4m = 16 ( divide both sides by 4 )
m = 4
