Which of the following uses distributive property? A. 0.4 x (2a - 0.3b) = 0.4 + (2a - 0.3b)

B. 0.4 x (2a - 0.3b) = 0.8a - 0.12b

C. 0.4 x (2a - 0.3b) = 0.8a x 0.12b

D. 0.4 x (2a - 0.3b) = (2a - 0.3b) / 0.4

sorry not knowing about that

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.
