Answer:
The coefficient of a²b³c is -720
Step-by-step explanation:
Given: 
Let 2a-b = x and 3c = y
General term of binomial expansion.
where, n=6 , r=1 ( because exponent of c is 1)
----------(1)
Now, we simplify (2a-b)⁵
The exponent of b is 3 and a is 2 .
If we take r=3 will get exponent of b is 3 and a is 2
So, put r=3
Substitute into equation (1)
Hence, The coefficient of a²b³c is -720
The steps are shown here.
1) Factoring
2) Completing the square
3) Quadratic Formula
4) Graphing
So basically the answer would either be 5 or -5.
First problem:
x 8
--- = ---
3 12
Then 12x = 24, and x = 2 (answer).
Please be fair to other students needing help. Present just one problem at a time.
The solution is simple 11*5/2. 11= the base or bottom of the triangle. 5=the high or side. the triangle is 1/2 of a rectangle so divide by 2. the solution is 27.5 units.
