-2 + 9i

Step-by-step explanation:

Start by performing the multiplication 4i(2i):  the end result is -8.

Then we have 6 + 9i - 8.

Combining ilke terms, we get:

-2 + 9i

-2 + 9i

Step-by-step explanation:

Start by performing the multiplication 4i(2i):  the end result is -8.

Then we have 6 + 9i - 8.

Combining ilke terms, we get:

-2 + 9i

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
