A4 in. by 5 in. photo is enlarged so that its width (shorter dimension) is 5 in. what is the length of the enlarged photo? 5.25 in. 6 in. 6.25 in. 7 in.

This problem can be solve by using ration and proportion, since you want to enlarge the picture by not distorting the image, the new dimensions should be in proportion with the old one.

Let x be length of the image

(5/40 = (x/5)

X = 5(5/4)

X = 6.25 in

Is there a picture of a graph or whatever that goes along with this?

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
