The perimeter of a rectangle is 96 yards and the length is 14 yards more than the width what are the dimensions of the rectangle

____ [38]

Answer:

17 yards and 31 yards.

Step-by-step explanation:

Since length is 14 more than width, lets call width: w and length: w+14

So perimeter is 96 so: 2w+2(w+14)=96

2w+2w+28=96 so 4w+28=96

4w=68 and finally w=17

So 17 yards and 31 yards.

What is the slope of the line that passes through the points A(-2,3) and B(-12,6)?

harina [27]

Answer:

The answer is

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(-2,3) and B(-12,6)

The slope is

$m = \frac{ 6 - 3}{ - 12 - - 2} = \frac{3}{ - 12 + 2} \\ = - \frac{3}{10}$

We have the final answer as

$- \frac{3}{10}$

Hope this helps you
