if x A y means x + (X+1) + (x+2) + (x+3) +...,
y times
express 12 A 3 in simplest form
12 + (12+1) + (12+2) = 39
well that aint right so..
To express 12 A 3 in simplest form, we need to calculate the sum of the terms according to the given pattern: x + (x+1) + (x+2) + (x+3) + ... + y times.
In this case, x is 12 and y is 3. So, we can rewrite the expression as follows:
12 A 3 = 12 + (12+1) + (12+2) + (12+3) + ... + 3 times
Now, let's calculate the sum by expanding the terms:
12 + 13 + 14 + 15 + 16 + 17 + 18
Adding these numbers together, we get:
12 A 3 = 105
Therefore, 12 A 3 in its simplest form is 105.
