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.
18/20 is 90%
You can use a calculator to divide 18 and 20 and you will get 0.9 which is 90%
Or. simplify by dividing the top and bottom by 2, to get 9/10 which is still 90%

Answer:
3xz5+2x+4y−2z
Step-by-step explanation:
2x−5y+3z5x+9y−2z
=2x+−5y+3xz5+9y+−2z
Combine Like Terms:
=2x+−5y+3xz5+9y+−2z
=(3xz5)+(2x)+(−5y+9y)+(−2z)
=3xz5+2x+4y+−2z
