Which of the following could represent the unit side lengths of a right triangle A 5,8,10

B 3,5,7

C 6,11,13

D 12,16,20

D 12,16,20

Step-by-step explanation:

The Pythagora's Theorem

On a right triangle with side lengths of a,b, and c, being c the hypotenuse, of the longest side, it follows that:

The set {a,b,c} is often called a Pythagorean Triple.

Testing every option:

A

89 = 100

Since equality is false, 5,8,10 are not the side lengths of a right triangle.

B

34 = 49

Since equality is false, 3,5,7 are not the side lengths of a right triangle.

C

157 = 169

Since equality is false, 6,11,13 are not the side lengths of a right triangle.

D

400 = 400

Since equality is true, 12,16,20 could be the side lengths of a right triangle.

D 12,16,20

4.6875 pounds

step-by-step explanation:

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6
