Step-by-step explanation:
Answer:
-3 is the answer because if we divide 15 by 5 we get 3 . So it is same only the question is -15 divide by 5 so the answer is -3
Step-by-step explanation:
9x^3+6x^2-3x
Cannot be simplified because there are no like terms but can be factored as
=3x(3x−1)(x+1)
This means the for every 2 units of red paint, there is 1 unit of blue paint
exg
in a mixture, mix a red and blue paint to get a type of purple that is the ratio of 2:1 (red:blue)
so exg if you wanted 3 gallons you would do 2 gallons of red+1 gallon of blue since 2+1=3
it could also mean quantity
there are 2 tiles painted red for every 1 tile painted blue resulting in 2 unit of red paint to 1 unit of blue
