Answer:

2(x+2) (x^2+3)

Step-by-step explanation:

2x^3+4x^2+6x+12

I will use factor by grouping

2x^3+4x^2   +6x+12

Taking 2x^2 from the first two terms and 6 from the last two terms

2x^2( x+2)  +6(x+2)

Now I can factor x+2 out

(x +2)(2x^2+6)

We see in the last term that we can factor out 2

(x+2) 2(x^2+3)

Rearranging

2(x+2) (x^2+3)

Find the value of each expression.<br> 6b2 – 5 if b = 3
snow_tiger [21]
The answer should be 31, if I’m doing this correctly.
6(3)2-5 (multiply 6 and 3, you get 18)
18(2)-5 (multiply 18 and 2, you get 36)
36-5 (subtract 36 and 5)

Mila [183]

Answer:

6.45 feet

Step-by-step explanation:

He starts 17 and 1/2 feet off the ground

Elevation relative to ground: 17 1/2

Then he increases the height by 4 and 3/4

Expression: 17 1/2 +4 3/4

Elevation relative to ground: 22 1/4

Next he decreases the elevation by 15.8 feet

Expression: 22.25-15.8

Elevation relative to ground: 6.45

The answer 6.45 feet from the ground

Answer:

The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true

The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false

Step-by-step explanation:

we have

2x-y=-5 -----> First equation

x+3y=22 -----> Second equation

Solve the system of equations by graphing

Remember that the solution of the system is the intersection point both graphs

The solution is the point (1,7)

The ordered pair (7,19) lie on the first line, so is a solution of the first equation

see the attached figure

<u><em>Verify each statement</em></u>

case 1) The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true

The statement is true

case 2) The ordered pair (7, 19) is a solution to the second equation because it makes the second equation true

The statement is false, because the ordered pair (7,19) not lie on the second line

case 3) The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false

The statement is true

case 4) The ordered pair (7, 19) is a solution to the system because it makes both equations true

The statement is false,because it makes only the first equation true
