Answer:
4.5 gallons.
Step-by-step explanation:
Multiply the volume value by 4.
In this case, you multiple 4.5 by 4 which equals 18.

Lets say that the two unknown integers are

and

.
We know the following things about

and

:


And, we want to find

.
To solve this, we'll use the expansion of the squared of the sum of any two inegers; this is expressed as:

So, given what we know about the unknown integers, the previous can be written as:

We can easily solve for

:
The answer is 168.
Another approach to solve the problem is, from the two starting equations, compute the values of

and

, which are 12 and 14, and directly compute their product; however, the approach described is more elegant.
Answer:
111.2
Step-by-step explanation:
The square root and the ^2 cancel each other out so the number stays the same or 111.2

It would be 20 years because if En is 100 Mark will be 25. 25 times 4 is equal to 100
