The answer is rather symbol just combine the like terms! -2X^2 has no like terms for it is the only exponent so cancel out C because it doesn't start with -2X^2. Next we add all variables with X but no exponent so 3X and -5x Add those together to get 3X +-5X which is -2X because the + is cancelled out so ghe equation is 3X-5X which equals -2X so get rid of everything but B. Finally to confirm it is B add all the basic numbers so the five and three to get eight. So (f+g)(x) = -2X^2 -2X + 8. The answer is B. (You guys said it was A so I changed it but now I know I am right.)
Eighth note is half of a quarter note, a quarter of a half note and an eighth of a whole note.
Answer:
the answer would be 15x+ 1
Step-by-step explanation:
The answer is A, 13. Since we know line DB is a median (the middle), it tells us that line BC must equal line AB. Simply just do 26/2.
45 minutes and 20 minutes have to compared.
45/20= 2,25
That tells me that if I multiply 20 minutes by 2,25 I get 45 minutes.
Thus if you travel 3 miles in 20 minutes you will travel 3*2,25 miles in 45 minutes. 3*2,25=6,75
