How to I find x and y.

x=9

y=14

Step-by-step explanation:

Your picture shows that the two angles are congruent so:

2[(2x+27)]=90

4x+54=90

4x=36

x=9

Your picture shows the two horizontal lines as congruent also so:

4y-19=y+23

4y-19+19=y-y+23+19

3y=42

y=14

good luck!

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.
