Answer:
x^4 - 11·x^2 + 18 = 0
I use Vieta's formulas
-9·(-2) = 18 and -9 + (-2) = -11
(x^2 - 9)·(x^2 - 2) = 0
(x + 3)·(x - 3)·(x + √2)·(x - √2) = 0
Since we find the cube root of 216, we get 6, which is the answer
Answer:
77*
First we are going to take our given number, 25* and 78* and add them together.
25* + 78* = 103*
And subtract our answer, 103*, from 180*.
180* - 103* = 77*
77* is our missing angle. To prove it, we add angle measures a, b, and c, to make the number 180*
25* + 78* + 77* = 180*
Another way to write it is . . .
180* - (A + B) = C

Answer: 4
-5+4=-1
-1+4=3
3+4=7
I hope this is good enough:
Answer:
m=2
Step-by-step explanation:
(x1,y1)=(−7,−6)
(x2,y2)=(−3,2)
m=
y2−y1 / x2−x1
= 2−−6 / −3−−7
= 8/4
m=2
