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
It doesn't. One third multiplied by three fourths is one fourth or .25
Answer:
Step-by-step explanation:
Using the Z theorem, the upper angle on the right = 60 degrees.
The angle which includes 3x is 120 because this is a parallelogram and consecutive angles must add to 180. So 180 - 60 = 120
The angle above the 3x is 120 - 3x
120 - 3x + 90 + 2x = 180 These angles make a straight line line. Combine.
210 - x = 180 Subtract 210 from both sides.
- x = 180 - 210 Combine
-x = - 30 Multiply both sides by - 1
x = 30
