Is the following a proportion?

2/3 and 10/20

a) proportion

b) not a proportion

B) Not a proportion

Step-by-step explanation:

By definition, a proportion indicates that two fractions or two ratios are equal.

Therefore, keeping the definition above on mind, you must divide the numerator by the denominator of each fraction. If the result is the same, it is a proportion, if it is not the same, then it is not a proportion:

It is not a proportion.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

25% is the answer
