tangle
1 answer:
Create expressions for the length and width of the rectangle.
- length (l): x - 6
- width (w): x
Perimeter: 2l + 2w
Substitute (x - 6) for l and (x) for w.
Distribute 2 inside the parentheses.
Combine like terms.
Add 12 to both sides.
Divide both sides by 4.
Substitute 16 for x into the length and width of the rectangle.
- length: (16) - 6 = 10
- width: (16) = 16
