B. $9.50

C. $10.00

D. $10.50

B

Step-by-step explanation:

76/8 = 9.5

Choice B

The answer is B

Step-by-step explanation:

Because if you take the total which is 76 and divide by the time spent would be 8 you get 9.50. Hope this helps!

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.
