Please I need help with this ASAP. A Chef thought of a very challenging formula for a combination of codes for his locker. He can use n numbers to set the code to his locker. He wants to hide all his recipes in it. He wants to know how many codes he can make so that he can change the password to his locker every week. He came up with the following formula but he forgot how to simplify it.
2nC1 + 2nC2 + 2nC3 + ... 2nCn + ... 2nC2n
Simplify this formula for him to tell him the number of combinations he can use in terms of n.

step-by-step explanation:

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

the correct answer is 1.7

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
