176 and 180 all the other numbers are good
For this case we must simplify the following expression:
We eliminate the parentheses taking into account that:

So:

We add similar terms taking into account that:
Equal signs are added and the same sign is placed.
Different signs are subtracted and the major sign is placed.

Answer:

Answer:
22 hours
Step-by-step explanation:
8•x= 176
Divide both sides by 8 and you get-
Y=22
The volume of a sphere is 4/3 * pi * r³ so substitute the values in
4/3 * pi * 2³
4/3 * pi * 8
32/3 * pi
The volume is either 32/3pi units³ or 33.49 units³ (they're the same value)
I hope this helps!
8 * 5 = 40
40 * 4 = 160
160 * 12 = 1,920
Answer: $1,920
