The answer is D in that problem
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.
I’m not sure what you mean. But if you are talking about, 3x-15=2 the answer would not be x-5 it would be x= 17/3. So that means your answer would be not true. If I’m explaining the wrong thing comment and lmk :) !
First, convert 15'66'' to degrees. Every degree is 60' and every minute (') is 60''. Thus, 15' x (1° / 60') = 0.25°and 66'' x (1' / 60'') x (1° / 60') = 0.01833°Add all the measurements in degrees including the 32° from the given. That is, 32° + 0.25° + 0.01833° = 32.268°Rounding the answer to the nearest hundredth gives us 32.27°.
