6
Step-by-step explanation:
12/2=6

Then you will have a = -12+5
Simplify and you get A= -7

70 and 90 beats per minute
Answer:
yes the answer is B
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
(f+g)(x) is 3x^2 + 3x/2 - 9
(f+g)(x)=f(x)+g(x)=x/2-3+3x^2+x-6= 3x^2 + 3x/2- 9
