Answer: Here are a few ways that you could apply expressions or equations to a camping trip.
The cost of renting a cabin could be: C = 50N + 70, where C is the cost and N is the number of nights.
The number of tents needed could be: T = P/3, where T is the number of tents and P is the number of people going.
The amount of marshmallows needed could be: M = 5P, where M is the number of marshmallows and P is the number of people.

The length of the photograph is <u> 10 </u> inches.
Explanation:
Given, Width of a photograph is x.
Length of the photograph is 3 inches longer than its width. i.e. x + 3.
Area of the photograph = x(x+3)
If its area is 70 square inches, then
x(x+3)=70
x(x-7)+10(x-7)=0
(x+10)(x-7) =0
x+10=0; x-7 = 0
x = -10 and x = 7
Width of the photograph must not be in negative value. So, we can ignore –10.
Therefore, width of the photograph, x = 7 inches.
Now, the length of the photograph = 7 + 3 = 10 inches.
Thus, the required length of the photograph is 10 inches.
