Step-by-step explanation:

Part 1) A rectangular prism has a length of 3 inches, a width of 5 inches, and a height of 1 inches.

What is the volume of the prism?

we know that

The volume of the rectangular prism is equal to

substitute the given values

Part 2)

A rectangular prism has a length of 3 1/2 inches, a width of 5 inches, and a height of 1 1/2 inches.

What is the volume of the prism?

we know that

The volume of the rectangular prism is equal to

we have

substitute

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

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.
