Answer:
(13+x)cm
Step-by-step explanation:
Given data
Length of sides
1cm, 5cm, 7cm
Since the shape is four-sided and the fourth side is not given, let the fourth side be x
so
The perimeter of the polygon is
P= 1+5+7+x
P= 13+x
Hence the perimeter of the polygon is
P= (13+x)cm
The answer is 18
75/x = 100%/24%
x/75 = 24/100
you’re answer is 18

Answer: n=7
Step-by-step explanation:
n=number.
2n-5=9
2n=14
n=7
4/5+18/x=8
18/x=8-4/5
18/x=36/5
90=36x
x=5/2
