Answer:
3m(1-2m)(1+2m+4m^2)
Step-by-step explanation:
It would come out to 3x = 3x so it would be infinitely many solutions
Answer:$570
Step-by-step explanation:If it is 900 for 2 walls, and they need 6 walls, then multiply 900 by 3. They would use 2700 bricks for 6 walls. Multiply 2700 by 0.10 to get the price for all the bricks, 270 dollars. If labor to build each wall costs 50 dollars then multiply that by 6 and add it to the 270 dollars. It costs 570 dollars to build 6 walls
If 1 line completely overlaps the other line, they are the same line with infinite solutions.....so ur answer would be the 4th one
