CD is the altitiude to △ABC, AC= 25, and CD= 24. What is the length of AB?

Step-by-step explanation:

if we know two sides of the triangle, we can find the third one using the Pythagorean Theorem.

a² + b² = c²

In this case, we need to find the value of c, which is always the hypotenuse or the longest side. We find the longest side to be AB, since it is opposite the largest angle in the triangle, the right angle.

We substitute the values of a and b in the equation. Note, a and b are interchangeable, but c is NOT!. C must always be the longest side for the formula to work.

25² + 24² = c²

625 + 576 = c²

1201 = c²

c =

c ≈ 34.6554469023

range is infinite on both x and y axis positive and negative

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
