K/3 + 4 -2k = -9k
First you add 9k to both sides
<span>k/3 + 4 -2k = -9k
</span>            +9k   +9k
<span>k/3 + 4 + 7k = 0
</span>
Now subtract 4 from both sides
k/3 + 4 + 7<span>k = 0
</span>        -4           -4
k/3 + 7<span>k = -4
</span>
Now multiply 3 by both sides
k/3 + 7<span>k = -4
</span>x3     x3    x3
k +21k = -12

Now add k + 21k
22k = -12

Now divide both sides by 22
<span>22k = -12
</span>-----    -----
 22      22
k = -6/11

give the length and width in whole inches of three different rectangles that each have an area of 48 in. squared
lozanna [386]
To find the length and width of 3 different rectangles that have an area of 48 square inches, you can use the factor pairs that result in 48.

The reason is that to find the area of a rectangle you multiply two dimensions.

2 in x 12 in
3 in x 8 in
4 in x 6 in

On all these either one could be the length and the other the width.
