The simplified expression is 
Step-by-step explanation:
The given expression is:

Multiply the items in the numerator together ( 15b * 8 = 120 b). Also multiply the items in the denominator together ( 4 * 9a²b² = 36a²b²). The expression thus becomes:

Divide both the numerator and the denominator by 12b:

The expression finally becomes:

Answer:
86% Decrease
Step-by-step explanation:
3.70 times x= 3.20 3.20 divided by 3.70= 0.86
2.74x7.5=20.55=20.550
That's all of your answers.
?!?! whaaatt confused lol
Think of it as two rectangular prisms next to each other, and find the volume of each one separately.
The big one on the left has a volume of 4 * 12 * 6, or 288.
The smaller one on the right has a volume of 2 * 6 * 6, or 72.
288 + 72 = 360. 360 cubic feet of water are needed.
