Let, the width = x
length = 2x - 4
Perimeter = 2(l+w)
Substitute their values,
72 = 2(x+2x-4)
72 = 2(3x-4)
6x - 8 = 72
6x = 80
x = 80/6
x = 13.3
In short, Your Answer would be 13.33 cm
Hope this helps!
Answer:
This question does not make sense
Step-by-step explanation:
2x+5=12
Subtract 5 from both sides
=2x=7
Divide by 2
X=2/7
Answer:
x = -8/5
Step-by-step explanation:
-3(x+4) -> -3x-12
-3x-12=7x+4
-7x
-10x-12=4
+12
-10x=16
16/-10 = -8/5
-8/5 = x
