Any help with this? I need help solving.

By AAS or AAA congruence, you can prove it.

I hope it will be useful .

Step-by-step explanation:

angleG=angleE (given)

Corresponding opposite angles formed by the transversal are equal! i.e., angleFDG=angleDFE or vice-versa..

And the side is common! or you can prove it by AAA criteria (two pairs of equal angles made by the transversal)

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.
