the length is 3 inches less than twice the width and the permiter is 42 inches. Find dimensions July 29, 2021 by Neala the length is 3 inches less than twice the width and the permiter is 42 inches. Find dimensions
Answer: Here Step-by-step explanation: length = x width = 2x – 3 Perimeter = 2length + 2 width 2x + 2(2x – 3) = 42 2x + 4x – 6 =42 6x – 6 = 42 Add 6 to both sides 6x = 48 Divide both sides by 6 x = 8 Length = 8 inches Width = 2(8) – 3 = 16-3 = 13 inches Reply
Answer:
Here
Step-by-step explanation:
length = x
width = 2x – 3
Perimeter = 2length + 2 width
2x + 2(2x – 3) = 42
2x + 4x – 6 =42
6x – 6 = 42
Add 6 to both sides
6x = 48
Divide both sides by 6
x = 8
Length = 8 inches
Width = 2(8) – 3 = 16-3 = 13 inches
