Answer:
x = 6
Step-by-step explanation:
10x - 15x + 5 = -45 + 20
→ Simplify the 10x - 15x
-5x + 5 = -45 + 20
→ Simplify the -45 + 20
-5x + 5 = -25
→ Minus 5 both sides from to isolate -5x
-5x = -30
→ Divide by -5 from both sides from to isolate x
x = 6

25-29 ok so first do 9-5 equals 4
(a-b)^2 = a^2-2ab+b^2
(8-5i)^2 = 8^2-2(8)(5i)+(5i)^2
= 64-80i+25i^2
i^2=-1
So
= 64-80i+25(-1)
=64-25-80i
= <em><u>39 - 80i</u></em>
which is your answer :)

Use the law of cosines:
c² = 8² + 11² - 2•8•11 cos(37°)
c² ≈ 44.4402
c ≈ 6.66634
