The area of a mirror is 225 square inches, it's width is

inches. will the mirror fit in a space that is 15 inches by 16 inches? explain.

NO. The mirror will not fit in a space that is 15 inches by 16 inches

Solution:

Given that area of mirror is 225 square inches

Converting the above mixed fraction we get,

Let us find the length of mirror

The area of mirror is given as:

area of mirror = length x width

Substituting the given values,

Thus length of mirror is 16.36 inches

Will the mirror fit in a space that is 15 inches by 16 inches?

NO. The mirror will not fit in a space that is 15 inches by 16 inches

Because length of mirror is 16.36 inches whereas the given space is 15 inches long

16.36 > 15 so the length of mirror will not fit inside the space

Also width of mirror is inches which is less than the given space whose width is 16 inches

13.75 < 16 so the width of mirror will not fit inside the space

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.

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
