Answer:

A. 20

Step-by-step explanation:

Firstly, you have an equation where x is unknown.

It is said to find the result of this equation if x is 5.

That means you have to substitute 5 instead of x in your equation.

That will be:

3*5+4*5-15

When you calculate that, you get number 20.

Answer:

41 2/3 feet

Step-by-step explanation:

The sum of wall lengths (in feet) is ...

(12 1/4) + (10) + (12 1/4) + (10 -2 5/6)

= (12 + 10 + 12 + 8) + (1/4 + 1/4 - 5/6)

= 42 + (3/12 + 3/12 -10/12)

= 42 - 4/12 = 42 - 1/3

= 41 2/3 . . . feet

The answer is above.
Additional note 1:
${4}^{3} = 4 \times 4 \times 4 = 16 \times 4 = 64$
Additional note 2:
In the answer I filled in "0" at the place where "n" was. This is because the question tells us n=0
