Hello there!

(8 + 3i)(3 + 5i)

We must distribute each number/variable to the others in the opposite parenthesis.

8(3 + 5i) = 24 + 40i
3i(3 + 5i) = 9i + 15i^{2}

Combine like-terms.
40i + 9i = 49i.

Now, put your simplified answer in Standard Form;
15i^{2} + 49i + 24

This is your answer.

I hope this helps!

The points (3, 24) and (7, 56) represent points of a function where y, the number of photographs, varies directly with x, the nu
tester [92]
(3,24)(7,56)
slope = (56 - 24) / (7 - 3) = 32/4 = 8

y = mx + b
slope(m) = 8
(3,24)...x = 3 and y = 24
now we sub
24 = 8(3) + b
24 = 24 + b
24 - 24 = b
0 = b

so ur equation is : y = 8x + 0...or just y = 8x

to find ur answer, take ur answer choices and sub them into y = 8x and whichever one is true is ur answer.
