5 0

Answer:

13

Step-by-step explanation:

<em>1. Distribute each term in the first binomial to each term in the second binomial,</em> <em>FOIL (first, outer, inner, last)</em>

(3 - 2i) (3 + 2i)

9 + 6i - 6i - 4i^{2}

<em>2. Simplify </em>

9 - 4i^{2}

<em>3. Solve for i. </em>i^{2} = -1

9 - 4 (-1)

9 + 4 = 13

hope this helps!

DanielleElmas [232]

Answer:

Angle A and L are 140 degrees each.

Step-by-step explanation:

Since GO and AL are parallel to each other, we can use the same side interior theorem to figure out angle A and L. Let's focus on GA first. We know that same side interior angles are supplementary (sum is 180 degrees). We know angle G is 40 degrees, so to figure out angle A, you do 180-40 which equals 140. So angle A is 140 degrees. You repeat this process for OL and you should also get 140 degrees for L.
