The answers are 2. B, 3. D, 4. C, and 5. A.

Step-by-step explanation:

Step 1:

For question 2. 4+4n = -12.

We subtract both sides by 4 to get

4+4n-4 = -12-4, 4n = -16, n = -4

For question 3. 4n=-12.

We divide the entire equation by 4 to get

\frac{4n}{4} = \frac{-12}{4} , n = -3.

Step 2:

For question 4. \frac{n}{4} = -12.

We multiply both sides by 4 to get

\frac{n}{4} (4)= -12(4).

n = -48.

For question 5. \frac{n}{4} -4 = -12.

We add 4 to both sides to get

\frac{n}{4} -4 +4= -12+4, \frac{n}{4} = -8.

n = -32.

So the answers are 2. B, 3. D, 4. C, and 5. A.

Plzz I asked this three times! The Functions r and s are defined as follows.
Lana71 [14]

Answer:

s(r(2)) = 6

Step-by-step explanation:

You would first solve for r(2). You then input r(2) which equals -2 into s(r(2)).

r(x)= -2x + 2

r(2)= -2(2) + 2

r(2)= -4 +2

r(2)= -2

s(x)=x² + 2

s(r(2)) = (-2)² +2

s(r(2)) = 6
