Answer:
1/343
Step-by-step explanation:
If you multiply 1/7*1/7*1/7 (1/7^3) then you would get 1/343.
You can use the pythagorean theorem.
Now lets write out what we know.
Shorter leg = x
Longer Leg = x + 7
Hypotenuse = x - 7
Now solve for x
x = 28
Since you know x = 28, which is the shorter leg, you can solve for the rest by just plugging in 28 where x is located. For instance, longer let is x + 7 so
28 + 7 = 35
Functions are accurate through having one x intercepts which is how you can find which are functions or not.
