There are no solutions.
Step-by-step explanation:
cuz they ain't all real numbers
im wrong
Answer: k=54/79
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 16/3k from both sides.
Step 3: Subtract 5/2 from both sides.
Step 4: Multiply both sides by 12/(-79).
See attachment for further explanation
Let r(cos O + i sin O) be a cube root of 125(cos 288 + i sin 288)
then
r^3(cos O + i sin O)^3 = 125(cos 288 + i sin 28)
so r^3 = 125 and cos 3O + i sin 3O = cos 288 + i sin 288
so r = 5 and 3O = 288 + 360p and O = 96 + 120p
so one cube root is 5 (cos 96 + i sin 96)
Im a little rusty at this stuff Its been a long time.
Im not sure of the other 2 roots
sorry cant help you any more
Answer:
130
Step-by-step explanation:
25+25 = 50
180-50=130
The next step is to ADD 10x to both sides!
