What does x equal? will give brainliest!

110

Step-by-step explanation:

triangle = 180° total so

180- 82 = 98

98 ÷ 2 = 49

y = 49

4 sided shape = 360° total

35 + 35 + 49 + 49 + 82 = 250

360 (total) - 250 = 110

hope this helps

the answer is. -82562234434584

step-by-step explanation:

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.
