Excel expects a + or = sign before math calculations.
Also, for arguments of functions (such as sqrt), parentheses "()" are used. Brackets "[]" are not acceptable.
That leaves only one remaining option.

Answer:
486 square units
Step-by-step explanation:
Use the surface area formula with the given numbers.
SA = 2(LW +H(L +W))
SA = 2(12·6 +9.5(12 +6)) = 2(72 +9.5(18)) = 486
The surface area of the box is 486 square units.
Step-by-step explanation:
you plug 0 into the (x,y) into the equation. if your finding x you plug in 0 for y and versa.
so y = 9x -3 im going to find x
0 = 9x -3 subtract -3 from both sides
-3 = 9x divide by 9
x = -3
X is pretzels and y is hot dogs
3x + 2y=195
x +15 =y
3x + 2(x+15)=195
5x=165
x=33
