-1
Step-by-step explanation:
x² + 6x + 8, x= -3
= (-3)² + 6(-3) + 8
= 9 + (-18) + 8
= 9 - 18 + 8
= - 1
Firstly, solve 38C15.
Then solve 42C12.
Compare your answers.
The goal here is to see if 38C15 = 42C12.
Here is the formula:
nCr = n!/(r!(n - r)!
Go for it.
5/2
Shown in picture above.
The answer is 1.79 × 10-3
What do you need help with, it looks complete to me.
