Factor completely 2x2 9x 4. (2x 2)(x 2) (2x 1)(x 4) (2x 4)(x 1) (2x 2)(x 4).
lozanna [386]

Factors of the given expression are (x+4), (2x+1)

Given expression is

2x^2 + 9x+4

<h3>What is a factor?</h3>

A factor is a number that divides another number completely.

Let us split the middle term as:

2x^2 + 8x + x+4\\\\2x(x+4)+1(x+4)\\\\(x+4) (2x+1)

Therefore, factors of the given expression are (x+4), (2x+1)

The diameter of the base of the cone measures 8 units. The height measures 6 units
daser333 [38]

For this case we can find the volume and area of the cone:

V = \frac {\pi * r ^ 2 * h} {3}

Where:

V: It's the volume

A: It's the radius of the base

h: It's the height

We have to:

r = \frac {8} {2} = 4 \ units\\h = 6 \ units

Substituting:

V = \frac {\pi * 4 ^ 2 * 6} {3}\\V = \frac {96 * \pi} {3}\\V = 32 \pi \ units ^ 3

On the other hand, the area of the cone is given by:

A = \pi * r * g +  \pi * r ^ 2

Where:

A: It's the radio

g: It is the generator of the cone.

g = \sqrt {h ^ 2 + r ^ 2} = \sqrt {6 ^ 2 + 4 ^ 2} = \sqrt {36 + 16} = \sqrt {52} = 7.2

SW:

A = \pi * 4 * 7.2 + \pi * 4 ^ 2\\A = 28.8 \pi + 16 \pi\\A = 44.8 \pi \ units ^ 2

Answer:

V = 32 \pi \ units ^ 3\\A = 44.8 \pi \ units ^ 2
