Which of these expressions CANNOT be simplified by combining like terms?
2 answers:
Answer:
The answers are :
<em>option 1,option 3 and option 4.</em>
Step-by-step explanation:
in first option:
clearly we could see that there are no like terms hence we could not simplify the expression.
in second option:
this expression could also be written as:
in third option:
as there are no like terms hence the expression can't be simplified.
in fourth option:
as there are no like terms hence the expression can't be simplified.
Hence option 1, option 3 and option 4 are the answers.

we can use properties of functions to find this out
for
if b is even, then the ends of the function go in the same directions (both up or both down)
if b is odd, then the ends of the function go in different directions (one up and one down)
if a is positive and b is even, then both ends point up
if a is positve and b is odd, then it goes from bottom left to top right
if a is negative and b is even, then both ends point down
if a is negative and b is odd, then it goes from top left to bottom right
given
a=5>0
b=4 which is even
so it has both ends pointing up
bottom right graph is yo answer
