For each expression, select all equivalent expressions from the list. (a) 4(5x-2)

1) 20x-2
2) 20x - 8
3) 9x-2
4) 4.5x-4.2

(b) 8y + 5y + 7y

1) 8y+12y
2) 12y-8y
3) 20y
4) 20+ y

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.

step-by-step explanation:

mark brainliest

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.

if i did my math right then the answer should but 108

the answer is  

c.

90.0π cm^2

hope you got it.
