The answer is D. say you have 21 split into 5 parts then you will have 5 4.2's. then take three of them and you get 12.6.
Answer:
-3.4p + 3p + 4
Step-by-step explanation:
Solve the parenthesis with the minus sign in front of it. Basically, inverse all of the operations within the parenthesis.
The -3q will become a 3q and the -4 will become a 4.
So now with the positive 3q and 4, you will just add those to the -3.4p
Therefore, the answer is -3.4p + 3p + 4

That would be -3a^7 Answer
Cos( A + B ) = cosAcosB - sinAsinB ;
cos( A + B ) / ( cosAsinB ) = ( cosAcosB - sinAsinB ) / ( cosAsinB ) = ( cosAcosB ) / ( cosAsinB ) - ( sinAsinB ) / ( cosAsinB ) = cosB / sinB - sinA / cosA = cotB - tanA ;
