Answer:
<em>$40 </em>will be the total cost of the ribbon.
Step-by-step explanation:
To find the cost of ribbon to be put on the edges of rectangular banner, we need to:
1. Find the perimeter of the rectangle.
2. Multiply the perimeter with the per foot cost to find the total cost.
Let us find the perimeter first:
Perimeter of a rectangle is given as:
Here, the dimensions of rectangle are 4ft by 6ft.
So, perimeter = 
It is given that per foot cost is $2.
Total cost of the ribbon = 
<em>$40 </em>will be the total cost of the ribbon.

Answer:
−2y3+4y2+18x+8
Step-by-step explanation:
Let's simplify step-by-step.
4(y2+2)+6x−2y3+12x
Distribute:
=(4)(y2)+(4)(2)+6x+−2y3+12x
=4y2+8+6x+−2y3+12x
Combine Like Terms:
=4y2+8+6x+−2y3+12x
=(−2y3)+(4y2)+(6x+12x)+(8)
=−2y3+4y2+18x+8
For this one use the slope formula, (y2-y1)/x2-x1)
Just to have them in one place, here are the ordered pairs
(-1,-2) (2,2)
You can do these in any order, here is how I did the problem:
(2--2)/2--1)
Your y intercepts are 2 and -2
The x are 2 and -1
Now reduce. Since you are subtracting a negative, it turns into a positive.
(2+2)/(2+1)
4/3
There is our slope: rise 4 run 3 or as a fraction 4/3.
Hope this helps!
