Answer:
B) x^2y + 7
Step-by-step explanation:
we are given

We can use grouping method to factor it


now, we can factor common terms


so, we get



we can see that x^2y+7 is one of factor
Total of all angles should equal 360 degrees. So 360-132-68-66=94, angle F is 94 degrees.
The composition of a function and its inverse is x. So an easy approach to solve this question is to find the composition of a function with itself. If the composition results in an answer "x", then this will mean that function and its inverse are the same.
Finding the composition for 1st option:

Since the composition of the function with itself is not x, the function and its inverse are not the same.
Similarly, we can find the compositions of next 3 functions with themselves. The results of compositions are listed below:
(gog)(x)=g(g(x)) = x
(hoh)(x)=h(h(x))=

(kok)(x)=k(k(x))= x
Thus the option 2 and 4 are the correct answers i.e. these functions are the same as their inverse functions.
Answer:
54 or 15
Step-by-step explanation:
x = any number
x = 3
First solve the brackets:
2x + 3
(2x3) + 3 = 9
2x = 6
I can help you up to here because the question isn't worded properly.
If you are multiplying then it would be: 9x6 = 54
If you are adding then: 9+6 = 15
Hope this helps!
So i think you gotta see where the point is ay and if it isnt rig
