Answer:
36 - 8i
Step-by-step explanation:
(3 + 5i)(2 - 6i) ← expand factors using FOIL
= 6 - 18i + 10i - 30i² → i² = - 1
= 6 - 8i + 30
= 36 - 8i

Answer:
If two ratios are equivalent to each other, then they are said to be in proportion. For example, the ratios 1:2, 2:4, and 3:6 are equivalent ratios.
Step-by-step explanation:
Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.
