The correct answer is answer B 10
Answer: (x+3) (x-20)
Step-by-step explanation:
Take the formula of a rectangle and use substition to fill in the information you already know.
A= LxW
57f = L x 3.8f
Now use the balance method to figure out what the length is. You're really just doing algebra.
57f= L x 3.8f
57f ÷ 3.8 f = L x 3.8f <span>÷ 3.8f
</span>
15f= L
ANSWER: The length of the sidewalk in 15 feet.
CHECK:
A= L x W
A= 15f x 3.8f
A= 57 feet
Least 8.334
67/8

Greatest 8 4/9
