Answer:
<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:
1. When adding you just add the numbers from the same space so
3 7
10 45
2. Same as adding but the opposite
2 1 2
3 1 6
1 2 1

Answer:
f(5) = 75
Step-by-step explanation:
The function is f(x) = 2x^2 + x(100 - 15x).
Evaluate this function at x = 5: replace each instance of x with 5:
f(5) = 2(5)^2 + 5(100 - 15·5)
Order of operations rules require evaluating the expression enclosed in parentheses first. We get:
f(5) = 2(5)^2 + 5(100 - 15·5)
= 50 + (100 - 75), so that:
f(5) = 50 + 25 = 75
f(5) = 75
