A binomial expansion is given by (a + b)^n = ∑nCk * a^(n - k) * b^k, k = 0, 1, 2 , . . . n
The third term is the term for k = 2.
The third term = 4C2 * (3x^2)^(4 - 2) * (2y^3)^2 = 6 * 9x^4 * 4y^6 = 216x^4y^6
Therefore, the coefficient of the third term is 216.
Answer: Its the 4th choice

-12 + 8 = -4
4. 6/8, 5. 3 5/8, 6. 7 7/8, 7. 72 months and 2,190 days
Answer:
3×9×4
Step-by-step explanation:
The volume for a box is b×h×w
With a bit of trial and error, you will quickly find out that the height and width, are small numbers.
When you try 3 for the height you will see that it works.
3×3=9 this is the length
the width is one inch more than the height so for
3×9×4=108
