If you multiply the length of both sides of a rectangle by 5, how much times bigger will the area of the new rectangle be? if you multiply the length of all three sides of a rectangular prism by 8, how much times bigger will the volume of the new prism be? write an equation to describe each situation and give a new example to demonstrate the equation works.

step-by-step explanation:

£56

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.

step-by-step explanation:

infinity is the answer
