Find the equivalent expression by drawing a line from the left column to the right

Gala2k [10]

Answer/Step-by-step explanation:

$2(3x - 1) = 2*3x 2*-1 = 6x - 2$

$(x*y)2 = (xy)2 = 2xy$

$2(2x - 3) = 2*2x 2*-3 = 4x - 6$

$3x + 4x + 2 = (3x + 4x) + 2 = 7x + 2$

$7x - 7 = 7(x) - 7(1) = 7(x - 1)$

$x(6 + 9) = x(15) = 15x$

$2 + 9x + 1 + 3x = (9x + 3x) + (2 + 1) = 12x + 3$

$4(x + 2) + x = 4x + 8 + x = 4x + x + 8 = 5x + 8$
