Given x^2 -4x+4 is a factor of the polynomial 2x^4 - 11x^3 +68x-80, completely factor the polynomial using algebraic methods.​

Answers

Answer 1
Answer:

2x^4-11x^3+68x-80

2x^4-4x^3-7x^3+14x^2-14x^2+28x+40x-80

2x^3(x-2)-7x^2(x-2)-14x(x-2)+40(x-2)

(x-2)(2x^3-7x^2-14x+40)

(x-2)(2x^3-4x^2-3x^2+6x-20x+40)

(x-2)(2x^2(x-2)-3x(x-2)-20(x-2))

(x-2)(x-2)(2x^3-3x-20)

(x-2)(x-2)(2x^2+5x-8x-20)

(x-2)(x-2)(x(2x+5)-4(2x+5))

(x-2)(x-2)(2x+5)(x-4)

(x-2)^2(2x+5)(x-4)

3x - 20 + 3x + 5 = 111

Combine like terms
6x - 15 = 111

Add 15 to each side.

Evaluate
6x = 126
x = 21

Plug x back into the equation for angle EFG.
EFG = 3x -20
3(21) - 20
EFG = 43 degrees

Answer:

[tex] m\angle EFG =43\degree[/tex]

Step-by-step explanation:

[tex] m\angle EFG +m\angle GFH = m\angle EFH\\\\

(3x-20)\degree + (3x+5)\degree =111\degree \\\\

(3x-20+3x +5)\degree =111\degree \\\\

(6x-15)\degree =111\degree \\\\

(6x-15) =111 \\\\

6x = 111 + 15\\\\

6x = 126\\\\

x = \frac{126}{6}\\\\

x = 21\\\\

m\angle EFG = (3x-20)\degree\\\\

m\angle EFG = (3\times 21-20)\degree\\\\

m\angle EFG = (63-20)\degree\\\\

m\angle EFG =43\degree\\[/tex]

y = x2 + 2x

3x + -y = 24

Answers

Answer:

The following are the LINEAR functions.

[tex]2x\:+\:4\:=\:3x\:-\:8[/tex][tex]y = 3x - 2[/tex][tex]1[/tex][tex]3x\:+\:-y\:=\:24[/tex]

Step-by-step explanation:

We know that linear functions are the equations with a straight line graph in an XY plane.

Also, a linear function is a function of the form

[tex]f(x)=mx+b[/tex]

where m is the slope and b is the y-intercept. The only power of the variable is 1.

So, from the given expressions we can determine that:

1) [tex]y^2=\:5x\:+2[/tex]

[tex]y^2=\:5x\:+2[/tex]  is NOT a linear function because the power of y is 2, hence the graph won't be a straight line. Therefore, it is not a linear function

2) [tex]2x\:+\:4\:=\:3x\:-\:8[/tex]

[tex]2x\:+\:4\:=\:3x\:-\:8[/tex]

[tex]x=12[/tex]

This is a linear equation is an equation of a straight line, written in one variable.  The only power of the variable is 1

3) [tex]y = 3x - 2[/tex]

[tex]y = 3x - 2[/tex] is a linear function because it is of the form [tex]f(x)=mx+b[/tex] and the power of its x and y variables is 1. Hence, the function has a straight line graph.

4) [tex]y\:+\:x^2\:=\:12[/tex]

[tex]y\:+\:x^2\:=\:12[/tex] is NOT a linear function because the power of x is 2, hence the graph won't be a straight line. Therefore, it is not a linear function.

5) [tex]y\:=\:x^2\:+\:2x[/tex]

[tex]y\:=\:x^2\:+\:2x[/tex] is NOT a linear function because the power of x is 2, hence the graph won't be a straight line. Therefore, it is not a linear function.

6) [tex]1[/tex]

[tex]1[/tex] is a constant function and a constant function is also considered linear in this context, as it is a polynomial of degree [tex]0[/tex] or is the [tex]0[/tex] polynomial.

7) [tex]3x\:+\:-y\:=\:24[/tex]

[tex]3x\:+\:-y\:=\:24[/tex] is a linear function as the power of its x and y variables is 1. Hence, the function has a straight line graph. Therefore, it is a linear function.

In a  summary, the following are the LINEAR functions.

[tex]2x\:+\:4\:=\:3x\:-\:8[/tex][tex]y = 3x - 2[/tex][tex]1[/tex][tex]3x\:+\:-y\:=\:24[/tex]

Sorry if this isnt enough, but i am sure.

Answer:

D.  11 < x < 19.

Step-by-step explanation:

The third side x is between 11 and 19 cm.

Consider sides AB (length 4) and BC (length 15) of the triangle.

Consider the angle between AB and BC is slightly less than 180 degrees.  To get from point A to point C, we have to travel almost the entire length of A to C, which is from A to B and then B to C, so a bit less than 19 cm.

Consider the angle between AB and BC is slightly more than 0 degrees.  To get from point A to point C, we subtract the length of AB (because we're already further along BC), so 15 - 4, a bit greater than 11.
