Answer:
45 degrees
Step-by-step explanation:
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.
Answer:
5x
Step-by-step explanation:
4(2x+3)-3(x+4)
4(2x) + 4(3) - 3(x) - 3(4)
8x + 12 - 3x - 12
8x - 3x + 12 - 12
5x
