Sonja [21]

Answer:

B) 5 + 17i is your answer.

Step-by-step explanation:

In order to write this equation as a complex number in standard form, you must first simplify each term.

<em>Apple the distributive property.</em>

21 - 4i - 1 * 16 - (7i) + 28i

<em>Multiply -1 by 16.</em>

21 - 4i -16 - (7i) + 28i

<em>Multiply 7 by -1.</em>

21 - 4i - 16 - 7i + 28i

<em>Now simplify by adding terms :)</em>

<em>Subtract 16 from 21.</em>

5 - 4i - 7i + 28i

<em>Subtract 7i from -4i.</em>

5 - 11i + 28i

<em>Add -11i and 28i.</em>

= 5 + 17i
