Answer:

Step-by-step explanation:

Answer:
-560a^4b^3
Step-by-step explanation:
Given:
(2a - b)^7
By using Binomial theorem:
128a^7 - 448a^6b + 672a^5b^2 - 560a^4b^3 + 280a^3b^4 - 84a^2b^5 + 14ab^6-b^7
Here the fourth term is -560a^4b^3 !
I think a and c. I really don’t know tho
(7/4) / 4 = x / 3 or 4 / (7/4) = 3 / x
=======================
6(8-7) + 3 = 3 + 6(8-7)....commutative property
7.5
Using the Pythagorean theorem you can determine this answer! Let me know if I’m wrong!
