Solve the absolute value inequality: [X + 12[ +5 <27 Isolate the absolute value by subtracting 5 from both sides.
18+71<27
18+71<22
|x + 12[ < 22
|x + 121 > 22

Option C.

Step-by-step explanation:

The given absolute value inequality is

Isolate the absolute value by subtracting 5 from both sides.

Therefore, the correct option is C.

We can further solve this, to find the solution of the given inequality.

Subtract 12 from each sides.

The solution of given inequality is .

after simplifying it i got: -36.25 as my answer. hope that !

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
