Answer:
l = P/2 -w
Step-by-step explanation:
P=2(l+w)
Divide each side by 2
P/2 = 2(l+w)/2
P/2 = l+w
Subtract w from each side
P/2 -w = l+w-w
P/2 -w =l
<h3>Answer:</h3>
13 years old
<h3>Explanation:</h3>
Let g and m represent grandfather's age now and my age now. The relation 5 years ago was ...
... g -5 = 5(m -5)
The relation in 3 years will be ...
... g +3 = 3(m +3)
Subtracting the first equation from the second, we get ...
... 8 = -2m +34
... 2m = 26 . . . . . add 2m-8
... m = 13
My age now is 13.
