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
Answer:
I think it would be 7 dnejeias
The answer would be A) 14 - 12i
Simplify ( 3 - 7i + 11 - 5i )
Gather like terms ( 3 + 11 ) + ( -7i - 5i )
Simplify ( 14 - 12i ).
Answer:
I would compare the right angel to the left
then determine the position of how it would fit in side
identify my measurements
then complete the math
length x width divided by degree of angel
It would be 2.1×10 to the power of 13
