112 is the answer. I am not really sure what the parenthesis are for, but those answers in the parenthesis are wrong.
Hi there!

The two trapezoids are similar, so we can determine a common scale factor:
OL/UR = NM/TS
9/3 = 6/2
3 = 3
Trapezoid ONML is 3x larger than UTSR, so:
RS = 4, LM = y
3RS = LM
3 · 4 = y = 12.
Find x using the same method:
3UT = ON
3(2x+1) = 4x + 9
6x + 3 = 4x + 9
2x = 6
x = 3.
When leading coefficient is 1 , the root will be an integer for g(x) = 0
Option 4 is the right answer.
<h3>What is a Polynomial Function ?</h3>
Functions of independent variable in which the variable can appear more than once with different powers.

Let this represents the polynomial function
where 
Then the according to rational root theorem ,
The root of the function is given by

So when leading coefficient is 1 , the root will be an integer for g(x) = 0
Option 4 is the right answer.
