Can somebody help me I have not been paying attention

The answer is D.

Step-by-step explanation:

It have 5 different surface. I will name them as front, back, left, right and down. It's easier for you to see.

Front: 36*50= 1800

Back: 14*36=504

Left: 14*48/2=336

Right:14*48/2=336

Down:36*48=1728

Then, we add everything together and get the answer.

1800+504+336+336+1728=4702.

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.
