Answer:
Step-by-step explanation:
<u>Given expression:</u>
<u>Multiply both sides by the conjugate of the denominator to get rid of the fraction:</u>
- (1 + i)(3 - 4i) / (3 + 4i)(3 - 4i) =
- (3 + 3i - 4i - 4i²) / (9 - 16i²) =
- (3 - i + 4) / (9 + 16) =
- (7 - i) / 25
Answer:
x = -2
Step-by-step explanation:
6(x+7)=30
6x+42=30
6x=-12
x=-2
For this case we have the following ordered pairs:
(6, 9)
(4, 6)
The scale factor can be found in two different ways:

Therefore, the scale factor is given by:
Answer:
The scale factor of the dilation is 1.5
Answer: 72 degrees for a, 108 degrees for b
Step-by-step explanation: Since the ratio of a to b is 3 to 2, 3x+2x would be 180 degrees. Performing addition and division, we would get 36 for x, and substituting it would get 72 degrees for a and 108 degrees for b. Hope this helps! (Could I please have brainliest?)
