Answer:

B. $2x^2+4x+11$

Step-by-step explanation:

The given expression is

$2x^3+3x-22 \div x-2$

We use synthetic division to obtain;

2 0 3 -22

2| 4 8 22

2 4 11 0

The quotient is $2x^2+4x+11$

The correct chice is B

What is the slope of a line perpendicular to the line whose equation is 6x+y=66x+y=6. fully reduce your answer?

shepuryov [24]

It looks like your equation repeated twice. I'm assuming it's 6x + y = 6.

I'm going to put your equation into slope-intercept form: y = - 6x + 6.

For the slope to be perpendicular, we do the opposite reciprocal of the slope given. So your slope of a perpendicular line is 1/6.

Answer:

$x(x + 1)$

Step-by-step explanation:

$\frac{2x + 1}{ \frac{1}{x} + \frac{1}{x + 1} }$

Make denominators same:

$\frac{2x + 1}{ \frac{x + 1}{x(x + 1)} + \frac{x}{(x + 1)} }$

Add the numerators:

$\frac{2x + 1}{ \frac{x + 1 + x}{x(x + 1)} }$

$\frac{2x + 1}{\frac{2x + 1}{x(x + 1)} }$

Apply the rule:

$\frac{a}{ \frac{b}{c} } = \frac{a \times c}{b}$

Therefore,

$\frac{(2x + 1)\times x(x + 1))}{2x + 1}$

Cancel out common factor of 2x+1:

$x(x + 1)$
