Answer:

r = 4

Step-by-step explanation:

Simplifying

3r + -3 = 9

Reorder the terms:

-3 + 3r = 9

Solving

-3 + 3r = 9

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '3' to each side of the equation.

-3 + 3 + 3r = 9 + 3

Combine like terms: -3 + 3 = 0

0 + 3r = 9 + 3

3r = 9 + 3

Combine like terms: 9 + 3 = 12

3r = 12

Divide each side by '3'.

r = 4

Simplifying

r = 4

$A)9-8i$

Explanation

$9-\sqrt[]{-64}$

Step 1

Let's remember that

A complex number is an object of the form

$a+bi$

where a and b are real numbers and

$\begin{gathered} i^2=-1 \\ i=\sqrt[]{-1} \end{gathered}$

$\begin{gathered} 9-\sqrt[]{-64} \\ 9-\sqrt[]{-1\cdot64} \\ 9-\sqrt[]{-1}\sqrt[]{64} \\ 9-8\sqrt[]{-1} \\ 9-8i \end{gathered}$

therefore, the answer is

$A)9-8i$

I hope this helps you
