Suppose that the length of a certain rectangle is four centimeters more than three times its width. If the area of the rectangle is 39 square centimeters, find its length and width.

13 cm and 3 cm

Step-by-step explanation:

The area of the rectangle is 39 cm^2, so the length and width must multiply to equal 39. Since the length, or L, is 4 cm more than 3 times the width, or W, which makes an equation like this, L=3W+4

In this case, 13 is 4 more than 3 times of 3, or 9, since 9+4=13. So, the length of the rectangle is 13 cm while the width is 3 cm.

Hope this helps!

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
