Step-by-step explanation:
-2 (4x -15) -3 (5x^2 +7x +6 ) = -15x^2 -29x-12
-2 (7x +1 ) -5 (3x^2 +3x +3) = -15x^2 -29x -12
(-7x^2 -21x + 13) -(8x^2+8x+25) = -15x^2 -29x -12
(-17x^2+2x-3)+(2x^2-31x-9) = -15x^2- 29x -12
Answer:
- Deck's width is 6 feet.
- The area is 72 sq. ft.
Step-by-step explanation:
First, label it out:
- Length: 12 ft.
- Width: ?
- Area: ?
Then, we add up 12 twice (Since the length is on 2 sides):
- 12 + 12 = 24
- 36 - 24 = 12
- 12 - ? = ?
Now, we write down a 6 in the ?:
Width = 6.
We are not done!
Now, we have to solve for area.
