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.
The product of 12 and the sum of a number and negative 3 is 12(x - 3)
<h3>How to represent algebraic expression?</h3>
An algebraic expression is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, multiplication etc.).
In other words, an algebraic expression is a mathematical statement that contains a combination of numbers, symbols, variables and mathematical operators.
Therefore, the product of 12 and the sum of a number and negative 3 is as follows:
let
the number = x
Hence,
12 × (x + (-3))
12 × (x - 3) = 12(x - 3)
