I believe the answer is 81x^4-16x^2 difference of squares
Answer:
3
Step-by-step explanation:
We can choose three ways:AB, AC, BC, as the order is not important.
Or you can calculate 3C2=(3×2)/(1×2)=3
£26.4 because 10÷3 is 3.3 requiring and 3.3×8 is 26.4
49c^2 - 25d^6
(7c)^2 - (5d^3)^2
(7c + 5d^3)(7c - 5d^3)
The answer is: (7c + 5d^3)(7c - 5d^3).

<span><em>[To get this answer, first make pounds into ounces. There are 16 ounces in a pound. Multiply 2 (pounds) and 16 (ounces in a pound) to get 32 ounces of red beads. Next, do the same to the 1 3/4 pounds of green beads: 1 3/4 (pounds) times 16 (ounces in a pound) make 28 ounces. Last add 32 (oz) + 28 (oz) + 10 (oz) together to get the total weight of her supplies: 70 oz OR 4.375 lbs OR 6 oz. It's up to you which answer (they are the same but in different forms) you want to use.]</em>
