20. A rectangle is eight inch long and its diagonal is ten inches. What's the width of the rectangle?
(A) 3 inches
(B) 6 inches
(C) 4 inches
(D) 5 inches

B

Step-by-step explanation:

In this case you would use the pythagoram theorem.

A^2+B^2=C^2

8^2+B^2=10^2

64+B^2=100

subtract 64

B^2=36

square root both sides

B=6

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.

,, add !
