A dependent means t-test determines if the differences between scores on the pretest and post-test measures differ significantly from Zero(0).
Benefits of pre-test measurements
This design is superior to the post-test-only control design because it adds pre-tests. Addition of pre-test: Improve your design ability to detect effects. You can investigate the impact of interventions on various sublevels of pretesting.

In PEMDAS, there is no parentheses in this equation, so we move on to exponents.
-5^2 is 25
Now, we divide -15/-3 then we get 5

25+5+17 would be 47
Your answer should be 47!
Hope this helps (:
