Answer:
22.63
Step-by-step explanation:
v = √64 * h
= √64 * 8
= √64 * √8
= 8 * 2√2
= 16√2 = 22.63
14+6x=13, or further 1+6x=0
2+3(2x+4)=13,
Distribute the 3 into the parenthesis:
2+6x+12=13
Now combine like terms: 14+6x=13.
You can also write this as 1+6x=0 by subtracting 13 to the left, though it might not be necessary.
80
