7 0

Answer:

2a^2 + 3a - 1 ,

Step-by-step explanation:

I am assuming you mean

2a^3-a^2-7a+2

By long division:

a - 2 ) 2a^3 -   a^2 - 7a +  2 ( 2a^2 + 3a - 1 <------- Quotient

          2a^3 - 4a^2

                     3a^2 - 7a

                     3a^2 - 6a

                                -a + 2

                                -a + 2

                                 . . . . .

How do you graph a linear equation with two variables? Y= -3x-4
Minchanka [31]

First, lets break up the equation into pieces.

The first variable is slope, in your case here, we have a slope of -3 or -3/1.

The other variable is the y-intercept, which is where place on the graph where you plot (0,X), in your case here we got (0,-4). That is the y-intercept.

to graph it you have to plot the y-intercept, and then identify the slope.

Here is an example.

Find the value of x, then use that value to determine each angle measure of the triangles below.
olganol [36]

Answer:

x =8

The angles are

3x= 24

7x+4 =  60

13x-8 =96

Step-by-step explanation:

The sum of the angles of the triangle is 180

3x+ 7x+4  + 13x-8  =180

Combine like terms

23x -4 = 180

Add 4 to each side

23x -4+4 =180+4

23x =184

Divide by 23

23x/23 = 184/23

x =8

The angles are

3x= 3*8 =24

7x+4 = 7*8+4 = 56+4 = 60

13x-8 = 13*8-8 =104-8=96
