Answer:
B.
f(x) and g(x) are closed under subtraction because when subtracted, the result will be a polynomial.
Step-by-step explanation:
Assume m>=n WOLOG
Are also a polynomial in general, but maybe in a different degree
Closure under subtraction means, for all polynomials, under the operation of subtraction, it also belongs to polynomials
Answer:
X=25
Step-by-step explanation:
Remove parentheses
7x - 5x - 40= 10
Merge the similar terms
2x - 40= 10
Constantly move to the right side and change characters
2x = 10 + 40
Addition
2x = 50
Divide both sides of the equation by 2
x = 25
So, there will be 40 green cars. if we want the ratio to be 1:3, we will need there to b three times as many silver cars as green cars: 40*3=120.
we already have 20 silver, so we need to add 120-20, that is 100 silver cars!
