Answer:
A, B and D are true statements.
Step-by-step explanation:
We are given a binomial expansion
Now we will check each option
Option A: The coefficients of and both equal 1.
If we see first and last term of the expansion, This statement is true.
Option B: For any term in the expansion, a + b = n.
Let we take 3rd term of expansion
Here, a=n-2 and b=2
If we do a+b = n-2+2=n
a+b=n is true statement.
Option C: For any term x^ay^b in the expansion, a - b = n.
Let we take 3rd term of expansion
Here, a=n-2 and b=2
If we do a-b = n-2-2=n-4≠n
a-b=n is false statement.
Option D: The coefficients of x^ay^b and x^by^a are equal.
If we take second term from beginning and last of the expansion.
This statement true.
All that is needed is for you to graph the points and if they form a line, they will be collinear. If not, they will not be collinear.
Answer:
(2x+3)(5x-9)
Step-by-step explanation:
10x^2-3x-27
10x^2 + 15x - 18x - 27
(5x)(2x+3)-9(2x+3)
(2x+3)(5x-9)
Hope this helps!
The area of the circle is πr², ie. 144π.
The volume of the cilinder is 12×144π = 1728π cm³.
