Rafiq, a Tunisian cafe owner living in the 3rd century B.C., owns a growing restaurant on Cape Bon in the Mediterranean Sea. After consulting with bricklayers from nearby Carthage, Rafiq has decided to expand his establishment's patio. He will lay bricks in the patio following the pattern shown in the illustration. Rafiq reasoned that each brick would have a length, (x) and a width, (y). In deriving an expression for the total perimeter of the patio, he came up with the following:
4(x + y) + 12(x + y) + 2(3x + 5y) + 2(5x + 7y)
Which of the following is an equivalent expression to the total perimeter of the patio?
A.4x + y + 12x + y + 6x + 5y + 10x + 7y
B.4(xy) + 12(xy) + 2(8xy) + 2(12xy)
C.4x + y + 12x + 12y + 6x + 10y + 10x + 14y
D.4x + 6y + 12x + 12y + 6x + 10y + 10x + 14y

None of them
Because original one
4(x + y) + 12(x + y) + 2(3x + 5y) + 2(5x + 7y)=
4x+4y+12x+12y+6x+10y+10x+14y=
32x+40y
and rest of them are:
A. 4x + y + 12x + y + 6x + 5y + 10x + 7y = 32x+14y
B. 4(xy) + 12(xy) + 2(8xy) + 2(12xy) = 56xy
C. 4x + y + 12x + 12y + 6x + 10y + 10x + 14y = 32x+37y
D. 4x + 6y + 12x + 12y + 6x + 10y + 10x + 14y = 32x+42y

D would be correct if it began 4x + 4y....the 6y doesn't make sense but the rest of the equation does

none of the work, the first part has to be 4x + 4y, everything else in c is right, though

None of the above....OR (D), IF it really read 4x +4y to begin with.
