So (f-g)(x) = 3x2 + x, so when x = 2, the function is 14
What is the number line i'm sorry but i can help without a number line that this question is based off of.
Yes it is. Input the numbers into the pythagorean theorem,

and if they equal each other it is a right triangle.
Answer:
This is physics. By the way look the explanation.
Step-by-step explanation:
The formula of Potential Energy is E=mgh, where m is the mass of the object, g the gravitational, and h the height of the object. Given that the potential energy of the object is 150 Joules at 3 meters height, Represent m=E/(g*h), considering g=9.8 m/s^2(Because this value was used for the first object), we get m=150/9.8/3=5.102
Rounding to 2 decimals` 5.10 kg
Divide the number that islf can divide by like 2 or 3 or 4 for exaples
