The volume of a rectangular prism whose dimensions are binomials with integer coefficients is modeled by the function V(x) = x^3
Levart [38]

Answer:

The missing dimension of the prism is (x-4)

Step-by-step explanation:

Here, we want to find the missing dimensions of the prism

To get the volume, we are to multiply three dimensions since we are talking about volume

Mathematically, to find the third dimension, we need to divide the original polynomial by the product of the two other dimensions

The product of the two other dimensions is;

(x-1)(x-9) = x^2-9x-x + 9

= x^2-10x+ 9

So we divide;

(x^3-14x^2+49x-36)/(x^2-10x+ 9)

We can use long division to get this

using long division, the answer here is x-4

Two of the angles of a triangle measure 40° and 100°. Classify the triangle
Ksju [112]

Hey there!

All of the given angles of a triangle will always add up to 180 degrees. Therefore, our angle measures are 100, 40, and 40. There are 3 types of triangle classifications based on angles.

Acute: all three angles are less than 90 degrees.

Right: one angle is 90 degrees.

Obtuse: has an angle that is greater than 90 degrees.

As you can see, we have one angle that is greater than 90, which is 100.

Therefore, this is an obtuse triangle.

I hope this helps!
