First, you can write that 1260 ÷ 15 = 84.
To prove this one way, you can show the multiplication of the quotient and divisor. If the division was correct, it would end up as the value of the dividend:
84 * 15 = 1260
1260 = 1260
To prove this another way, you can show 84 being added 15 times and seeing if it totals 1260:
84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 = 1260
1260 = 1260
Answer:
c
Step-by-step explanation:
Length (L): 3w + 8
width (w): w
Perimeter (P) = 2L + 2w
128 = 2(3w + 8) + 2(w)
128 = 6w + 16 + 2w
128 = 8w + 16
112 = 8w
14 = w
Length (L): 3w + 8 = 3(14) + 8 = 42 + 8 = 50
Answer: width = 14 inches, length = 50 inches
