The Pythagorean Theorem states that a^2 + b^2 = c^2 with a and b being lengths of legs and c being the length of a hypotenuse. So we can use our givens to solve for the remaining leg.
9^2 + b^2 = 15^2
81 + b^2 = 225
b^2 = 144
b = 12
Equivalent fractions for 3/4 are 6/8 and 9/12
Equivalent fractions for 4/5 is 8/10 and 12/15
You can factor it by using a method of your choice. I'll just use guess and check, because it's the easiest in this situation (for me). I need two numbers that multiply to 6, and add up to 5. Those two number are 2 and 3. 2 * 3 = 6, and 2 + 3 = 5. So, I can write the above equation as follows in factored form:

Then it's pretty easy to recognize the zeros because I just have to solve for each parentheses by doing this:

and


So, your zeros are at
-2 and -3.
Your answer is A. If any step doesn't make sense, hmu!
Answer:
64
Step-by-step explanation:
Euclide's theorem states that in a right triangle, the square built of the side lenght is equivalent of the rectangle with sides hypotenuse and projection of the same side lenght. In formula, given the measures on the triangle:

Answer:
2 m.
