Solve: |2 + 4x| 11
Select the appropriate response
A) [-13/4, 9/4]
B) x=9
C) x=3,x=6

Help, please!

Correct option is A) [-13/4, 9/4] .

Step-by-step explanation:

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] .

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

answer4 to the second power is 16

and 4 to the third power is 64,
