Answer:
4 sqrt(2)
Step-by-step explanation:
radical 50 - radical 2
I rewrite in terms of sqrt (means the same thing)
sqrt(50) - sqrt(2)
sqrt(25*2) - sqrt(2)
We know that sqrt (ab) = sqrt(a) sqrt(b)
sqrt(25)sqrt(2) - sqrt(2)
5sqrt(2) - sqrt(2)
Factor out the sqrt(2)
sqrt(2) (5-1)
4 sqrt(2)
Answer: 12
Step-by-step explanation:
12 is the most common element in the set.
The vertex form of the quadratic function f(x) = x² + 2x + 3 is given as follows:
f(x) = (x + 1)² + 2
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
In this problem, the function is:
f(x) = x² + 2x + 3
Completing the squares, we find the equation in vertex form, as follows:
f(x) = (x + 1)² + 2
As (x + 1)² = x² + 2x + 1, hence 2 has to be added to find the equivalent function.

Correct option is A) [-13/4, 9/4] .
<u>Step-by-step explanation:</u>
Here we have following equation as |2 + 4x| = 11 or , 
. We need to solve for the value of x .Let's find out:
We know that Modulus Function is both positive & negative for particular values of x , i.e.
|2 + 4x| is positive :
⇒ 
⇒ 
⇒ 
⇒ 
|2 + 4x| is negative :
⇒
⇒ 
⇒ 
⇒ 
Therefore , Correct option is A) [-13/4, 9/4] .
