Jane is going to fence her backyard. she 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. which of the following is the equation that jane can use to figure out how far back from the house she can fence in? a) 25(x + 25 ) = 120 b) x + 25 = 120 c) 25x = 120 d ) x + x + 25 = 120

She knows the length of the fenced in area would be 25 feet ( same length as her house, so she needs to find the length of the other two sides. Using X for the length of the sides she would use X + X + 25 = 120.

The answer is D.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
