Given that m || n, what must be true of the two lines? Check all that apply. Line mand line n have different slopes.
Line m and line n have different y-intercepts.
The lines have the same steepness.
Eventually the lines will intersect.
Line m and line n lie on the same plane.

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.

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105

just get this app called photo math it should be able to do those
