B. 12 inches
C. 16 inches
D. 20 inches

The answer is, D. 20 inches

hope this helps :)

D. 20 inches

Step-by-step explanation:

pythagorean theorem: a^2 + b^2 = c^2

the hypotenuse, the longest side, is equal to c.

plug in.

48^2 + b^2 = 52^2

2304 + b^2 = 2704

2304 - 2304 +b^2 = 2704 - 2304

b^2 = 400

sqrt(b^2) = sqrt(400)

b = 20

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

step-by-step explanation:

for volume, add base x height x width
