Answer:
21.9
Step-by-step explanation:
The altitude of an isosceles triangle bisects the base. So, x represents the hypotenuse of a right triangle with legs of 9 and 20. It can be found using the Pythagorean theorem:
x^2 = 9^2 +20^2 = 81 +400
x = √481 ≈ 21.932
The length x is about 21.9 units.

Answer:
exponential function f(x) is
Answer:
102 yards.
Step-by-step explanation:
If she walked 30 yards and 72 all you have to do is add them together wich is 102 yards. If thats how far she walked in all she probably walked the same length back unless she took a longer way or a short cut.
I hope this helps!
Answer:
The value of polynomial for x = 2 that is f(2) will be 32
Step-by-step explanation:
We have given polynomial ![f(x)=3x^2+8x+4](https://tex.z-dn.net/?f=f%28x%29%3D3x%5E2%2B8x%2B4)
We have to find the value of f(2)
We have to find the value of polynomial for x = 2
So for finding this value we have to just put x = 2 in polynomial
So f(2) will be ![f(2)=3\times 2^2+8\times 2+4=32](https://tex.z-dn.net/?f=f%282%29%3D3%5Ctimes%202%5E2%2B8%5Ctimes%202%2B4%3D32)
So the value of polynomial for x = 2 will be 32
