For the following right triangle, find the side length x.
1 answer:
Answer:
25
Step-by-step explanation:
We can use the Pythagorean Theorem to find the value of x,
The Pythagorean Theorem states that , where a and b are the legs and c is the hypotenuse.
We already know a and b’s value so we can substitute inside the formula to find the length of the hypotenuse.

Answer:
They most have common denominators.
Step-by-step explanation:
Let the following two rational expressions:
where p,a,q, b are integers, a and b the denominators are not 0, i.e.
We can add rational expressions only if their denominator is same.
That is why we find LCD to be .
Then,
Let the following two rational expressions:
where p,a,q, b are integers, a and b the denominators are not 0, i.e.
We can add rational expressions only if their denominator is same.
That is why we find LCD to be .
Then,
So, the correct answer is the last option that we can sum rational expressions if they have common denominator.
