Area = 1/2 x perimeter x apothem
Answer:
Step-by-step explanation:
Let’s say the third length is x. We can use the Pythagorean Theorem which states that a^2 + b^2 = c^2 where a and b are the legs and c the hypotenuse. Using Pythagorean Theorem, we can see that x^2 + 6^2 = 9^2. Solving we get that x^2 = 45 -> x =
I hope this helps!!! :)
Answer:
( x + 3)( x - 3)( x + y )( x - y )
Step-by-step explanation:
You can group the terms in pairs and factor each pair:
-x^2y^2 + x^4 + 9y^2 - 9x^2 = x^2(-y^2+x^2) -9(-y^2+x^2)
= (x^2 -9)(x^2 -y^2)
Each of these factors is the difference of squares, so can be factored as such:
= (x +3)(x -3)(x +y)(x -y)
it is an irrational not sure but i don't believe that it could be put in an ratio, so I say an irrational number
Answer:
3n>15
Step-by-step explanation:
So basically, this three times a number, 3n, is greater than 15. So, this is 3n>15.
