Mike is painting a backdrop for the school play. The rectangular backdrop is 60 inches by 48 inches. If his container of paint can cover 250 square feet, does he have enough paint to cover the backdrop?

Yes 240sq ft is only required.

Step-by-step explanation:

60 x 48 =2880 inch square

We convert to feet 1 ft = 12 inches

2880/12 = 240sq ft

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.

answer is x<
