Answer:
Step-by-step explanation:
The units are cubic feet or ft^3
V = L * W * H
L = 5.2
W = 4
H = 3.5
All dimensions are in feet.
V = 5.2 * 4 * 3.5
V = 72.8 ft^3
Answer:x=7
Step-by-step explanation: Set up 3x-1 equal to 20
Then do your usual distributing.
We have to find the domain of the given function

"The domain of a function is the set of input or argument values for which the function is real and defined"
Now, we have to find the values of 'x' for which the given function will be real and defined.
As we can observe that for any real number, the given function will be real and defined.
Therefore, the domain of the given function is
or
.
Or we can say that the domain of the given function is the set of all real numbers.
