Answer:

  9 ft

Step-by-step explanation:

Let x represent the shortest piece. Then the sum of lengths is ...

  x + (x +25) +3x = 40

  5x = 15

  x = 3

  3x = 9

The third piece is 9 feet long.

_____

<em>Check</em>

The pieces are 3 ft, 28 ft, 9 ft, so total 40 ft, as required.

Find the slope of (1,6) (-9,-20)
Arisa [49]

To find the slope of two points you use the formula: \frac{y_{2} -y_{1} }{x_{2} -x_{1} }

In this case we can assume that:

y_{2}  = -20

y_{1} =6

x_{2} = - 9

x_{1} = 1

Plug the above into the equation I gave you at the start and solve:

\frac{-20 - 6}{-9 - 1}

\frac{-26}{-10}

Now reduce:

\frac{26}{10}÷2

\frac{13}{5}

^^^Slope for these two points

Hope this helped!
