D. 25(x+25)=120

Answer 1

The question ask to find the equation and choose among the choices the best equation that Jane can use to figure out how far back from the house she can fence in and the best answer would be letter A. X+X+25 =120. I hope you are satisfied with my answer and feel free to ask for more 

Answer 2

Answer:

$25+x+x = 120$

Step-by-step explanation:

Given :She has purchased 120 feet of fencing and knows that she wants to fence in a rectangular area where one side will be the back of her house.

She knows her house is 25 feet across the back.

To Find : Which of the following is the equation that Jane can use to figure out how far back from the house she can fence in?

Solution :

Let the breadth of the house be x

Her house is 25 feet across the back.

Boundary to be fence = 25+x+x

We are given that She has purchased 120 feet of fencing

So, $25+x+x = 120$

Hence the equation that Jane can use to figure out how far back from the house she can fence in is $25+x+x = 120$
