(12-6i)-(-3-8i). First you have to combine like terms, to do that remove the parenthesis: 12-6i-3+8i (because there is a - in front of the second parentheses the signs inside change). Now combine like terms: 9+2i. So your answer is 9+2i :)

To celebrate a diners anniversary, the owners have made a 40 foot long sandwich. The sandwich is cut into three unequal pieces.
Ivahew [28]
Let x be he length of middle piece.
3x = length of longer piece.
x-5 = length of shortest piece.

x + 3x + x-5 = 40
5x - 5 = 40
5x = 45
x = 45/5
x = 9. ( Size of middle piece )

Given that the longer piece is 3 times the size of middle piece,

Longest piece = 3 x 9 = 27.

Size of longest piece = 27 feet
Size of middle piece = 9 feet
Size of smaller piece = 40 - (27+9)
= 40 - 36
= 4 feet.
Thank you.
