Answer:
The set
Step-by-step explanation:
We separate the left and right side of the equation, to create two new equations:
(1)
(2).
and then to solve Tanisha's original equation, we find the solution to the system that we got above.
The first step in solving the above system of equations is to take the value for 
from equation(1), and substitute it into equation(2) which gives us:
which is the same equation that Tanisha set out to solve.
Answer:
1920
Step-by-step explanation:
What we can do is split this into two sections: the volume of the rectangle and the volume of the square.
Rectangle: We can follow the equation V = lbh, so we have 14x8x10, giving us 1120.
Square: We can use the same equation, V = lbh, giving us 10x10x8 which is 800.
Final Answer: To get the full volume, we have to add these together, so, 1120 + 800 = 1920.
