The area of a rectangle is 144cm squared. if the length is 16cm. What's the perimeter?

50cm squared

Step-by-step explanation:

First we need to find the side lengths,

In order to find the area you do,

A = Length x height

we know that the area is 144 and the length is 16.

144=16 x height

144 = 16 x ?

So know we need to find the height, so we do 144/16= 9

so the height 9 cm.

The question is not asking for the height, but the peremeter.

Peremeter = (Length x 2) + (height x 2)

peremeter= 16 x 2 + 9 x 2

peremeter = 32+18

peremeter = 50 cm squared

so the peremeter is 50 cm squared.

hope this helps,

have a great day,

the answer is 14ft

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.
