2x=0 x-3=0
Step-by-step explanation:
2x^ 2 - 6x = 0,
Factor out 2x
2x(x-3) =0

Answer:
The numbers are 42 and 49
Step-by-step explanation:
Let's make it into a simple equation. Make the ratios into a single variable like this: 6x+7x=91. If you simplify it more you would get 13x=91. From here divide both sides by 13. This will result with x being 7. But the problem wants you to find 6x and 7x. If you multiply 7 with 6 you would have an answer of 42. If you multiply 7 with 7 you get 49. If you want to check add 42 and 49. If you get 91, this means that the answer is correct
the answer is the distributive property I think
