Answer:
D. The x value of 4 is paired with different y values
Step-by-step explanation:
x values cannot repeat.
15.38. 7, the number in the hundredths place, is turned into 8 due to the following digit, 5. Since it is equal to the minimum, 5, the previous number is rounded up.
Length (L): 2w + 6
width (w): w
Perimeter (P) = 2L + 2w
66 = 2(2w + 6) + 2(w)
66 = 4w + 12 + 2w
66 = 6w + 12
48 = 6w
8 = w
Length (L): 2w + 6 = 2(8) + 6 = 16 + 6 = 22
Answer: width = 8 ft, length = 22 ft
