Answer:
6d
Step-by-step explanation
First, you need to multiply 2d by 3, which you'll get 3d.
Next, multiply both numbers (2d and 3d) and you'll have 6d because 2 times 3 equals 6 but, since you have valuables you'd have to put d as the valuables of both numbers then multiply the numbers.
Simplify. Combine like terms
17k - 10k + 15
(17k - 10k) + 15
17k - 10k = 7k
7k + 15 is your answer

(2-5i)(4+7i)=2(4+7i)-5i(4+7i)=8+14i-20i-35i²
recall that i²=-1,
8-6i+35=43-6i
43-6i is the final answer
