Answer:
A
Step-by-step explanation:
The side lengths must satisfy the Pythagorean Theorem to be a right triangle. The formula is
where a is the smallest side, b is the medium side, and c is the largest side. Test each set of numbers.

This satisfies the theorem. Since this is a multiple choice question, only one solution is possible. A is the solution.
Answer: 24
explanation: mode is the value that repeats most often. so, in this case, 24 repeats the most often.
Answer:
42
Step-by-step explanation:
Let the number be "x"
We translate the word equation to algebraic equation.
First,
subtract 6 from me, so we have:
x - 6
Now,
Multiply by 2, so we have:
2(x-6)
Now,
Subtract 40, then divide by 4:

Now, you get "8", so equate this to 8, we get:

We now solve using algebra:

The number is 42
