40 x ( $84 / 8 ) = ( 40 / 8) x $84 = 5 x $84 = $420
Answer:
area = 5220 in²
Step-by-step explanation:
It's a little difficult to ensure accuracy without a diagram of the net, but from what you have said, the net appears to comprise of:
- 2 rectangles: 35 x 24
- 2 rectangles: 24 x 30
- 2 rectangles: 35 x 30
Therefore, the total area of the net is:
⇒ area = 2(35 x 24) + 2(24 x 30) + 2(35 x 30)
⇒ area = 5220 in²
The only solution here would be x=0. Multiplying 0 to both sides results in 0=0 which is technically correct.
Answer: -9
18/x = -2
⇔ x = 18/(-2)
⇔ x = -9
Step-by-step explanation:
A. 48 = 12 + 20 + x
If you use this equation then you can do 12 + 20 = 32 and then you can do 48 - 32 = 16 so x = 16
