Answer:
C
Step-by-step explanation:
Nope. Your problem is not irrational
There we have an information of two functions 
Using this two functions
, we need to find the composition of functions (h\circ g)(t).
The composition of two functions h and g is the new function , by performing g first and then performing h.



Composition of h and g (t) = 

First plugin the value of 


We know that
, we need to find h(3t+3),
That is, to replace t by 3t+3,

Now distribute 2 into 3t+3,

Now plug in 


Thus the solution is (D).
X = 4, You subtract the 5x to the other side then divide the 32 by 8 to get 4.
4/3 - (-3/4)
4/3 + 3/4
16/12 + 9/12
25/12 = 2 1/12
Hope I helped :)
