<h2>
-24 + 22i</h2>
Step-by-step explanation:
Use the FOIL method of multiplication of binomials:
(-4+2i)(7-2i) = -28 + 14i + 8i - (-4)i²
Note that i² = -1. Thus, - (-4)i² = +4, and we then have:
-28 + 22i + 4, or
-24 + 22i
Answer:
If you slice a rectangular pyramid parallel to the base, you get a smaller rectangle as the cross-section.
4x + 20 + 2x + 30 = 100
6x + 10 = 100
6x = 90
x = 18
