Which side lengths form a right triangle 30 POINTS!! I DONT HAVE MUCH TIME
Virty [35]

Answer:

To solve this problem, we can use Pythagorean theorem, it tells us that the square of the hypotenuse is equal to the sum of the square of the other two sides.

When we look at these side lengths, we can see that only the second answer is suitable because from the lengths, we can predict that 13 is the length of the hypotenuse, 5 is the length of the shorter leg and 12 is the length of the other leg, and when you actually calculate it, the result is correct as well:

5² + 12² = 25 + 144 = 169

13² = 169

So the answer is B

Help me please i need the correct answer
BaLLatris [955]

Answer:

First one is 25/2

Step-by-step explanation:

12×2+1=25/2

9×4+1=36/4

cross multiply and you get

100/

divide both by 2 and you get 50/4 then you divide both by 2 again and you get 25/2 because you can't reduce it anymore

Which set of ordered pairs represents a function?

C because the x coordinate cannot repeat in a function. One x coordinate can go into multiple y coordinates though.

Hope it helps

Use the slope formula to find the missing coordinate.
DIA [1.3K]

Let the missing value = x

Slope is the change in y over the change in x:

3 = (x-2)/ (8-3)

3 = (x-2) / 5

Multiply both sides by 5:

15 = x-2

Add 2 to both sides:

X = 17

The missing coordinate is 17
