Your answer would be the bottom right image. In the bottom right image, x is divided by 5 consistently. No function can be determined in the other tables.
Area of canvas= 113 square in
area of one side= 113/4=28.22
=28 square in
The answer is x=13 because the equations equal each other
Let length of the hypotenuse = 3x and length of given leg be x feet.
then (3x)^2 = x^2 + 648
8x^2 = 648
x^2 = 81
so x = 9 and 3x = 27
Hypotenuse is 27 feet and the leg equals 9 feet.
It depends on how many options you have
You multiply the total number of books you have time 5 because you can choose 5
