Answer:</h2><h2>Yes, the simplified form of 2 square root of 3 − 2 square root of 3 is rational.</h2>
Step-by-step explanation:
The given expression is 
After performing the subtraction operation, the result is 0 as the terms are equal and opposite in sign, they cancel each other.
Rational numbers are those which can be expressed in the form of fractions, decimals, e.t.c
Since 0 can be expressed as a fraction, it is a rational number.
For eg: 
= 0,
Hence the result of the given expression is a rational number.
1.
Height h = 240 feet
We insert it into formula.
Now we solve this for t:
We have two answers as the rocket will pass this height on it's way up and down.
2.
Height h = 0 feet
We insert it into formula.
Now we solve this for t:
We do not consider solution -1 as the time can not be negative. Our solution is 5s.
3.
Height at bottom of hill h = 0 feet
We insert it into formula.
Answer:
True
Step-by-step explanation:
Given

Does the location represent the x intercept?
The general point form of a function is (x,y)
When y = 0;
This represents that the function crosses the y axis.
And whenever the function crosses the y axis, we have the x intercept of the function
<em>Hence, the statement is true</em>
For this problem, you have to find the g(x) right?
The f(x) is already given, so all you have to do is multiply both sides by negative 1 (-1) to get the g(x) which is the opposite.
It'll look like this (g(x) = x^2 + 3x + 2)(-1)
Then the answer should be, g(x) = -x^2 - 3x - 2
