Which expression is equivalent to the expression for the perimeter of the larger garden. Select all the apply.
1 answer:
Answer:
Option A, 4X + 40 expression is equivalent to the expression for the perimeter of the larger garden
Step-by-step explanation:
The complete question is
A garden is 15 feet long by 5 feet wide. The length and width of the garden will each be increased by the same number of feet. This expression represents the perimeter of the larger garden: (x+15)+(x+5)+(x+15)+(x+5). Which expression is equivalent to the expression for the perimeter of the larger garden? Select all that apply.
- 4x+40
- 2(2x+20)
- 2(x+15)(x+5)
- 4(x+15)(x+5)
- 2(x+15)+2(x+5)
Solution
The expression for the perimeter of the larger garden:
If the given expression is expanded and solved, we get the following
Hence, option A is correct

<h3>What is the constant of proportionality?</h3>Firstly, there is a proportional relationship.
Two values x and y are said to be in a proportional relationship if x=ky, where x and y are variables and k is a constant.
The constant k is called the constant of proportionality.
Given;
x y
