Need fast dont understand #1 the ratio of the sides of a rectangle are 5: 4. if the perimeter is 36 feet, what is the width (smaller side) of the rectangle, in feet? just type the number for the width. do not type "feet" or anything else. #2 the length of a rectangle is 5 inches greater than its width. the perimeter of the rectangle is 54 inches. what's the length of the rectangle in inches? just type the length. give me a number. don't type "inches" or anything else.

#1 alright so if the ratio is 5:4 adding them together is 9 but we want 36 as the perimeter sooo

36/9=4

So multiply both the 5 and the 4 makes

20:16

The 20 and 16 show the total side of the length Andy width so we need to divide them by two so...

(20/2):(16/2)=10:8 so the width would be 8

Check:10(2)+8(2)=20+16=36 yay on to the next one!

#2 ok let's say the length is x, that means the width would be x-5 so the perimeter of that would be 4x-10. Sooo...

4x-10=54 || 4x=54+10 || 4x=64 || x= 16

So the length is 16 while the width is 11. Let's check in case.

16(2)+11(2)=32+22=54 yup :D

  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.

i think the correct option is the second option.
