Answer:
Step-by-step explanation:
Answer:
w = (p - 2l) / 2
Step-by-step explanation:
Step 1: Distribute
P = 2l + 2w
Step 2: Move 2l over
P - 2l = 2w
Step 3: Divide everything by 2
(p - 2l)/2 = w
And you have your perimeter equation in the term of <em>w.</em>
If one number is x the other is 4x. I read the sum of their reciprocals as ¼=1/x+1/(4x).
Multiply through by 4x: x=4+1=5. So the numbers are 5 and 20.
