3p + 6p = 9p.
It is the same as adding the numbers when you have the same terms (letters).
In this case, it is P.
Hope I helped:)

For binomials, follow the rule FOIL (first, outside, inside, last.)
4x^2 + -8x + - 8x + 16
4x^2 – 16x + 16
CP=12, CM=20. CP is the altitude of the triangle. ACP is a right triangle, so you can solve for CP using Pythagorean's theorem. CP=\sqrt(AC^2-CP^2)=\sqrt(15^2-9^2)=12. AM=AP+PM=9+16=25. Triangle ACM is another right triangle, and CM=\sqrt(AM^2-AC^2)=\sqrt(25^2-15^2)=20.
Answer:
The coefficient of variation after the tax is imposed is 0.033
Step-by-step explanation:
Given
--- mean
--- variance

Required
The coefficient of variation
The coefficient of variation is calculated using:

After the tax, the new mean is:



And the new variance is:



So, we have:




The answer is 45 you put the 4 and the 5 togther
