What is the product of (5 – 2i)(3 + i)? The product is .

15 - i - 2i^2

Step-by-step explanation:

(5 - 2i)(3 + i) = 5(3 + i) + - 2i(3 + i)

= (15 + 5i) + (-6i - 2i^2)

= 15 - i - 2i^2

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
