A+b+c=56
a=√625=25
b=2√81 = 2x9=18
c = 56-25-18=13
Answer:
(x-4)
Step-by-step explanation:
Since a square has 4 equal sides, the perimeter of a square is 4 times one of the sides (which is equal to adding all the sides together). So:
Perimeter = 4(a side) = 4x-16
a side = (4x-16)/4 = (x-4)
All you have to do is substitute the numbers in the variables so it would be
14/1-7+4(5)
=14-7+4(5)
But you have to do pemdas so you would start with multiplication so it would be
=14-7+20
=7+20
=27
