Answer:
x=-2
Step-by-step explanation:
4+8x=-12
-4 -4
8x = -16
/8 /8
x = -2
Answer:
Expand it.
(1+2i)^3 is equal to (1+2i)(1+2i)(1+2i).
Multiply everything out (being sure to multiply <em>every</em> term. (1+2i) * (1+2i) = 1+2i+2i+4i^2.
i is the square root of negative one, so i^2 is just -1. 1+2i+2i-4 is what you get from the first two, so now simplify that:
1-4 + 2i+2i = (-3+4i) and now multiply that by (1+2i):
(-3+4i) * (1+2i) = -3 - 6i +4i +8i^2.
Simplify again, and the answer is: -11-2i
Step-by-step explanation:
I hope this helps - really my only tip is don't spend time thinking about what i is, that just hurts your brain. Just remember that i^2 is equal to negative one, and treat it like regular multiplication and you will be fine.

haha thanks for the points btw the answer is. h2t=th6
Step-by-step explanation:
Answer:
- D. y + 10 = 1/8* (x + 32)
Step-by-step explanation:
Use the given points to work out the equation of the line.
<u>Find the slope:</u>
- m = (- 10 - (-4)) / (- 32 - 16) = - 6 / - 48 = 1/8
<u>Use (-32, - 10) and point- slope form:</u>
- y - (- 10) = 1/8*(x - (-32))
- y + 10 = 1/8* (x + 32)
Correct choice is D
