Answer:
l=48, w=20
Step-by-step explanation:
Let the width of the pool be w feet, then the length will be:
The area of the pool is 960 square feet.
This means that:
Expand and rewrite in standard form to get:
Factor to get:
We discard the negative value because magnitude is positive.
This means
When p=8, we can substitute it into the equation.
4x8-2
=32-2
=30
The system:
- 12 c + 3 d = 6
- 3 c + 6 d = - 9
----------------------
The 1st equation:
- 12 c = - 3 d + 6 / * ( - 1) ( multiple both sides by -1 )
12 c = 3 d - 6 / : 12 ( divide both sides by 12 )
c = d / 4 - 1/2
Answer:
C ) c = 1/4 d - 1/2
