Combine like terms
x^2 -9
A (103)(109)
=103*109
=(10*10*10)*(10*10*10*10*10*10*10*10*10)
=10*10*10*10*10*10*10*10*10*10*10*10
=1012
=1000000000000

Answer: 60
Step-by-step explanation:
144 beads divided by 3 would equal how many black beads there are, which is 48. 144 beads divided by 4 would be how many purple beads there are. which is 36. You would add the black beads and the purple beads, or 36 + 48, to get the total of both. 36 + 48 = 84. You would take the 144 beads total minus the 84 black and purple beads, which is 60.
