Answer:
40
Step-by-step explanation:
y = 50 + .4 x 40
y = 30 + .9 x 40
y = 66 for both equations
The correct answer would be the first choice. For each picture drawn, the total cost increases by $34.50.
The area of a square is expressed as the length of the side to the power of two, A = s^2. We were given the area of the enlarged photo which is 256 in^2. Also, it was stated that the length of the enlarged photo is the length of the original photo plus ten inches. So, from these statements we can make an equation to solve for x which represents the length of the original photo.
A = s^2
where s = (x+10)
A = (x+10)^2 = 256
Solving for x,
x= 6 in.
The dimensions of the original photo is 6 x 6.
