Well you could simplify the fraction(s) in question to their smallest form (where you can’t divide anymore without getting decimal answers) and see if they are equal to 1/4.
For example 2/8, you can divide both sides by 2 to simplify to 1/4, thus 2/8 is equivalent to 1/4.
Hope this helps!
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.
Let's represent our number as x.
x is being added to 6 * x², and it equals 12
Factor:
Solve for x:
Therefore,
x = -3/2 and 4/3.
Answer:
3
Step-by-step explanation:
The notation "f(4)" means you put 4 where x is in the algebraic expression, then do the arithmetic.
f(4) = 2·4 -5
= 8 -5
= 3
