9. The slope for this one is 21 bc y1-y2/x1-x2 is the slope formula and this can be used between any two points (I used the first two) -30-(-54)/ 7-11 which is -84/-4= 21

10. Rate of change is the same thing as slope so 4.5-5/18-20 which is -0.5/-2 which means the rate of change is 2.5

11. 23-39/1-3 which is -16/-2 which means the rate of change is 8

12. 5/4 is 1.25 so the sports drink costs 1.25$ each

Hope this helped :)

Find the perimeter of a rectangle with a length of 4x + 2 and a width of 2x

Answer:

12x+4

Step-by-step explanation:

To find the perimeter of any shape you just have to take the sum of all the sides.

In this case you would write:

4x+2 (side 1) +2x (side 2) +4x+2 (side 3) +2x (side 4)

Now you just have to simplify the expression which would give you:

12x+4 (after collecting like terms)

So the final answer will be 12x+4
