Answer:

Step-by-step explanation:

Perimeter of triangle =  4x - 3 + x + 9 + 8

                                   = <u>4x + x</u> -<u> 3 + 9 + 8</u>

                                  = 5x + 14

Area  = \frac{1}{2}*base *height

         = \dfrac{1}{2}*8*3x\\\\= 4 * 3x\\\\= 12x

Question
IRINA_888 [86]

Answer:

m=\frac{5}{3}

Step-by-step explanation:

Given the following question:

Point A = (-2, -9) = (x1, y1)
Point B = (1, -4) = (x2, y2)

To find the slope of a line, we will need to use the formula for slope or rise over run.

m=\frac{y2-y1}{x2-x1}
m=\frac{-4--9}{1--2} =\frac{5}{3}
m=\frac{5}{3}

The slope of the given line is indeed "5/3."

Hope this helps.
