Answer:
-5x-48
Step-by-step explanation:
First, simplify the first half,
(2x2-5x-7) --> (4-5x-7) --> (-5x-7+4) --> (-5x-13)
Then, simplify the second half,
(7x2+3) --> (7x5) --> (35)
Finaly put them together
-5x-13-35, subtract like terms
-5x-48
This is the most simplifyed it can get because of the variable.
