1. A

2. p=12

Step-by-step explanation:

5. A proportion is when two or more ratios are equivalent to each other and can be simplified to the same thing. For example, 1:3 and 2:6, or 1/2 and 5/10.

3:6 simplifies to 1:2. 5:10 simplifies to 1:2. This pair is a proportion and should be selected.

4:12 simplifies to 1:3. 6:18 simplifies to 1:3. This is also a proportional relationship.

20:5 simplifies to 4:1. 10:3 cannot be simplified any further without having a decimal. This is not proportional.

24:36 simplifies to 2:3. 8:9 cannot be simplified, This isn't a proportion.

6. 2:3 = 8:p

2 × 4 = 8

3 × 4 = 12

p = 12

Let's simplify 8:12 to make sure it's equivalent to 2:3.

8 ÷ 4 = 2

12 ÷ 4 = 3

2:3

Hope this helps!

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
