Cpctc represents a succinct statement of a theorem regarding congruent trigonometry, defined as triangles.
I believe you are expected to simplify. To do this all you do is group like terms (x, x², x³ etc.) and then simplify the coefficients.
13. 10z + 7z - 19z² - 5z² - 17z
first you can rearrange and group like terms (remember the bring the sign in front of each term with it). I would do it like this:
-19z² - 5z² +10z + 7z - 17z
Now simplify the coefficients:
-24z² + 0z
you can omit the 0z and your simplified answer is
-24z²
Main thing to remember here is that z and z² cannot be simplified together, nor can any variable that has an exponent because the exponent makes them differ.

Percentage = (1352/40929) x 100%
percentage = 0.03303281292 x 100%
percentage = 3.30%
Answer is 264
You just multiply at three numbers
