Answer:

(2x^2+1)(4x+3)

Step-by-step explanation:

8x^3 + 6x^2 + 4x+3

Split into two groups

8x^3 + 6x^2 + 4x+3

Factor out 2x^2 from the first group and 1 from the second group

2x^2( 4x+3) +1( 4x+3)

Factor out (4x+3) from each group

(4x+3) (2x^2+1)

Rearranging the order

(2x^2+1)(4x+3)

Line CD contains points A (4, -7) and B (4, 8). The slope of line CD is

mylen [45]

To find the slope, you divide the difference of the y-coordinates of a point on a line by the difference of the x-coordinates. It is expressed as:

slope = (y2 - y1) / (x2-x1)
slope = 8-(-7) / 4 - 4
slope = 15 / 0
slope = undefined <------ SECOND OPTION

The line should be vertical where the slope is undefined. Hope this answers the question. Have a nice day.

Find the median of the lower half and the median of the upper half.

Subtract these two values.

The data are 20, 25, 30, 30, 31, 40, 41, 49.
