Identify the surface area of the composite figure.
s = 524 in^2
s = 513 in^2
s = 477 in^2

Step-by-step explanation:

I've already done this question for you. You must be reposting it because the answer was not correct according to the way the computer was programmed to get the answer. I can only think that you don't count the interface between the cube and the larger figure at all. So let's do it that way.

Start with the cube.

The formal equation is Area = 5 * s^2

It has 5 equal sides each one measuring 3 * 3

Area = 5 * 3^2 =                                                                              45

Now go to the other figure

The front and back face measure 14*6*2                                = 168

Left and Right Sides are 2 * 6 * 8                                                 96

Top and Bottom              2 * 14 *8                                              224

Don't count the base of the cube at all so subtract 3*3             -9

Total                                                                                             524

If that does not work, please leave a note at the bottom of this question.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

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.
