the cost of the laminate flooring per square foot

the area of the kitchen

the labor fee

the cost of the laminate flooring for the entire room

see the procedure

Step-by-step explanation:

we have

This is a linear equation in slope intercept form

where

The slope m is equal to

The slope represent the cost of the laminate flooring per square foot

The y-intercept is equal to

The y-intercept represent the labor fee

The term (st) represent the area of the room (s and t are the dimensions of the rectangular kitchen)

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

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.
