1 2
- x -
2 3
You go a cross the road like 1x2 is 2. 2x3 is 6. The answer is 2/6.
Answer:
Let variable y be the unknown number. So triple a number means 3y. The difference (use minus symbol) of triple a number and 5 should be written as 3y −5.

Answer:
Step-by-step explanation:
Subtracting and adding functions is actually super intuitive. As a super simple example, if you had f(x)=5+x and g(x)=3 then (f-g)(x) = 5+x-3 = 2+x.
So you basically just add or subtract any like terms. So now with your two functions we can hopefully figure it out. let me know if there's anything you don't understand.
f(x) = x^2+2x-6
g(x) = x+5
(f-g)(x) = (x^2+2x-6) - (x+5) When subtracting you have to distribute the minus sign to the second function so -(x+5) becomes -x-5
(f-g)(x) = x^2+2x-6-x-5 So there's 2x-x and -6-5 which are x and -11
x^2+2x-6-x-5 = x^2+2x-x-6-5 = x^2+x-11
So that's the answer.
