Answer:
mass of substance A=1.789
mass of substance B=2.185

Answer:
n^2+2n+1
Step-by-step explanation:
-2-8-18-32-50
difference=-6-10-14-18
common differences=-4-4-4-4-4
-2-8-18-32-50
n^2=1,4,9,16,25
minus it
=-1,-4,-9,-16,-25
differences 2,5,7,9
common differences=2
2,4,6,8
so 2n+1
so the answer is n^2+2n+1
<u>3x³y - 14x²y - 7xy</u> = <u>3</u>x - 2 - <u>1</u>
7x²y 7 x
