What number would fill in the question mark?

36 would go in the question mark box. This is because you square each value from the left side to have it match up with the corresponding right side

7 squared = 7^2 = 7*7 = 49 is the upper left box

4 squared = 4^2 = 4*4 = 16 is the upper right box

5 squared = 5^2 = 5*5 = 25 is the lower left box

6 squared = 6^2 = 6*6 = 36 is the lower right box

d is correct

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.
