We have the total length of VW and we know that C lies somewhere on that line.
Therefore:
VC + CW = VW
z+13+z+8 = 61
2z+21=61
2z=61-21
2z=40
z=40/2
z=20
A. Because when you try to find something (per) you will divide
I hope this helps
<span>If you square a number that is less than 1.
For example, say your number was 1/2
the square of 1/2 is (1/2)^2 = (1/2)(1/2) = 1/4
