2 practices = 4 1/2 hours
The second graph, B is the answer
Answer:
Width = 15.
Length = 22.
Step-by-step explanation:
If the length is L then the width W = 1/2L + 4.
The perimeter = 2L + 2W, so
2L + 2(1/2L + 4) = 74
2L + L + 8 = 74
3L = 66
L = 22.
So W = 1/2 *22 + 4 = 11 + 4
= 15.
8t + 1 + (-4t) + (-6) = [8t + (-4t)] + [1 + (-6)] = (8t - 4t) + (1 - 6) = 4t - 5
