The correct answer is D.D. 8a^4b^3 + 6a^3b^5 - 2a^3b^4
You can tell this by the lead term alone. When you mutliply the term outside to the lead term, D is the only one that has that term.
2a^2b^3*4a^2 = 8a^4b^3
D. 8a^4b^3 + 6a^3b^5 - 2a^3b^4
Answer:
3.9
Step-by-step explanation:
cost = 24.40
subtract the cost of beads from the total cost.
24.40-8.8=15.6
divide that by four because there are 4 necklaces
15.6/4=3.9
