Answer:
Length ≈ 20 feet (rounded down nearest 10th feet)
Width ≈ 20 feet (rounded up to nearest 10th feet)
Step-by-step explanation:
Find Length and Width
Width = Length - 4 feet
Area = 42 ft²
Area = L x W
42 = L x (L - 4)
42 = 2L - 4
42 + 4 = 2L - 4 + 4
2L = 46
2L/2 = 46/2
L = 23
L ≈ 20 feet
Width = 23 - 4
Width = 19 feet
Width ≈ 20 feet
Answer:
y = 27
Step-by-step explanation:
The given are two similar triangles.
We can use the following equation to find the variables:
Cross multiply fractions
32*18 = 24(y-3)
576 = 24y - 72
add 72 to both sides
648 = 24y
divide both sides by 24
27 = y
Well you would divide distance by time and you should make sure that you do the trucks equation seperate from the cars equation other wise you would only get one answer and it looks like you need 2 so figure out the time an distance for each car then divide distance by time and that is your answer.
