I need to learn how to solve the problem above. And I really want to learn how to do it, not just the answer. Can someone please help explain it to me?

Alright. We need to first define a few symbols that I'm going to have to use to do this, so you don't get confused.
@ will stand in for the delta symbol, and x^y will mean x to the power of y.
You know that x@y means x^2 + xy +y^2.
You're given (3@1)@1
Working with the numbers inside the parenthesis
x=3 y=1
(3)^2 + (3)(1) + (1)^2
9 + 3 + 1 = 13
Now substituting 13 for x so we can finish the problem
(13)^2 + (13)(1) + (1)^2
169 + 13 + 1 = 183
183 is answer E.

Do the parentheses first.
Since y = 1, put y = 1 in your formula:
3Δ1 = 3²+3+1 = 13.
Now we want 13Δ1 = 13²+13+1= 169+14 = 183.
The answer is 183.

No simpler question than this :D.
x /\ y = x^2 + xy + y^2
so
(3/\1) = 3^2 + 3*1 + 1^2
= 9 + 3 + 1 = 13
now
(3/\1)/\1 = 13/\1
= 13^2 + 13*1 + 1^2
= 169 + 13 + 1
= 183

Simply plug in the numbers given to you for 3V1 (V = the triangle).
xVy = x ^ 2 + x * y + y ^ 2
3V1 = 3 ^ 2 + 3 * 1 + 1 ^ 2
3V1 = 9 + 3 * 1 + 1
3V1 = 9 + 3 + 1
3V1 = 12 + 1
3V1 = 13
Thus: The value of 3V1 is equal to 13. Whatever the values of xVy are, just put those in the formula where x and y occur; and remember to always use B.E.D.M.A.S. (Brackets, Exponents, Division, Multiplication, Addition, Subtraction).

permit x = # of applications with 12 bagels in each and each equipment then 20 - x could desire to be the form of applications with 6 bagels according to equipment. entire bagels = (luggage with 6) + (luggage with 12) 168 = (20 - x) 6 + (x)12 = one hundred twenty - 6x + 12x Simplifying... 40 8 = 6x 8 = x _ _ _ _ _ _ _ _ the possibility of Teresa getting chosen is a million/10, then Julie's danger is a million/9, so Teresa, then Julie is (product) a million/ninety. yet we additionally enable for Julie then Teresa, so a million/ninety +a million/ninety = a million/40 5.

I believe the answer is B - 13
i plugged in the 3 as x and y as 1 and i got 13
but i am unsure about the next part with the triangle 1
