Answer: D. 28
Explanation:
There are 8 toppings and you can choose 2 of the 8 topping
Which mean it’s 8 choose 2
8 choose 2 = (8 x 7)/(2 x 1) Meaning that there are 8 way to choose the first topping and 7 way to the topping
8 choose 2 = 56/2 = 28
Long way:
2(x-3)(x+3) = 2(x*x + 3*x - 3*x - 3*3)
2(x-3)(x+3) = 2(x^2 - 9)
2(x-3)(x+3) = 2x^2 - 2*9
2(x-3)(x+3) = 2x^2 - 18
Shortcut way:
Using formula (x+a)(x-a) = x^2 - a^2, where a = 3, in the case of (x+3)(x-3), so we have
(x+3)(x-3) = x^2 - 9.
Then, we multiply that by 2, which gives 2x^2 - 18.
Answer:
(3x+1)/(x^2-6)
Step-by-step explanation:
f/g(x)=f(x)/g(x)=(3x+1)/(x^2-6)
