Solve the polynomial equation by factoring. x^3+2x^2-9x-18=0

Answers

Answer:

This can be factored to (x + 3)(x - 3)(x + 2) = 0

So x is equal to 3, -3 and -2

Step-by-step explanation:

x³ + 2x² - 9x -18 = 0

Let's try dividing by (x + 3) as that looks like it might be a factor.  We'll use long division:

                    x²  - x - 6

        x + 3  }  x³ + 2x² - 9x -18

                    x³ + 3x²

                           -x² - 9x

                           -x² - 3x

                                -6x - 18

                                -6x - 18

                                         0

Perfect!  So (x + 3) is a factor, giving us:

(x + 3)(x² - x - 6)

the remaining quadratic can be factored more easily:

(x + 3)(x² - x - 6)

= (x + 3)(x² + 2x - 3x - 6)

= (x + 3)(x[x + 2] - 3[x + 2])

= (x + 3)(x - 3)(x + 2)

Now we can solve it easily as we know that's equal to zero, so x can be equal to 3, -3, and -2

If you notice each container has 4 balls

3 = 12

6 = 24

10 = 40

So, this means 1 container = 4 balls

x = 28

Divide by 4

28/ 4 = 7

Pleaee gimme brainliest

Answer:

7

Step-by-step explanation:

theres a loop of 4 balls per container

3 divide 12 = 4 balls

6 divide 24 = 4 balls

? divide  28 = 4 balls

10 divide 40 = 4 balls

when you divide its like dividing the balls into the containers so if you look at ? divide 28 = 4 balls it would equal 7

ex

1 divide 28 = 28 no

2 divide 28 = 13 no

3 divide 28 =  27.5 no

4 divide 28 =  7 yes  4 goes into 7

Question :-

A cylinder has a radius of 6 in and a height of 10 in. What is the surface area of this cylinder?

Answer :-

The surface area of the cylinder is 602.88 in².

[tex] \rule{180pt}{3pt}[/tex]

Diagram :-

[tex]\setlength{\unitlength}{1mm}\begin{picture}(5,5)\thicklines\multiput(-0.5,-1)(26,0){2}{\line(0,1){40}}\multiput(12.5,-1)(0,3.2){13}{\line(0,1){1.6}}\multiput(12.5,-1)(0,40){2}{\multiput(0,0)(2,0){7}{\line(1,0){1}}}\multiput(0,0)(0,40){2}{\qbezier(1,0)(12,3)(24,0)\qbezier(1,0)(-2,-1)(1,-2)\qbezier(24,0)(27,-1)(24,-2)\qbezier(1,-2)(12,-5)(24,-2)}\multiput(18,2)(0,32){2}{\sf{6 \: in}}\put(9,17.5){\sf{10 \: in}}\end{picture}[/tex]

Solution :-

As per the provided information in the given question, we have been given that the radius of the cylinder is 6 in. The height of the cylinder is 10 in. We have been asked to find or calculate the surface area of the cylinder.

To calculate the surface area of the cylinder, we will use the formula below :-

[tex]\bigstar \:\:\:\boxed{\sf{\:\:Surface \: Area_{(Cylinder)} = 2\pi r^2 + 2\pi rh \:\:}}[/tex]

Substitute the given values into the above formula and solve for surface area:

[tex]\sf:\implies Surface \: Area_{(Cylinder)} = 2\pi r^2 + 2\pi rh[/tex]

[tex]\sf:\implies Surface \: Area_{(Cylinder)} = (2)(3.14)(6 \: in)^2 + (2)(3.14)(6 \: in)(10\:in) [/tex]

[tex]\sf:\implies Surface \: Area_{(Cylinder)} = (2)(3.14)(36 \: in^2) + (2)(3.14)(60\:in^2) [/tex]

[tex]\sf:\implies Surface \: Area_{(Cylinder)} = (2)(113.04 \: in^2) + (2)(188.4 \: in^2) [/tex]

[tex]\sf:\implies Surface \: Area_{(Cylinder)} = 226.08 \: in^2 + 376.8 \: in^2 [/tex]

[tex]\sf:\implies \bf{Surface \: Area_{(Cylinder)} = 602.88 \: in^2}[/tex]

Therefore :-

The surface area of the cylinder is 602.88 in².
