5. In the picture shown, point D is the image of point A after a clockwise rotation about point C by 136 . Points B, C, and D are collinear. Which statement below must be true?

hhh hmh hmmm yeah i got nothing

Step-by-step explanation:

c. 4 1/4 pounds

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
