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] .

45

step-by-step explanation:

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
