Select all polynomials that have (x-3) as a factor.

Mathematics

Alchen [17]3 years ago

Answer:

Below.

Step-by-step explanation:

Substitute x = 3 into each polynomial and see if the value of the polynomial is zero. If it is zero then x-3 is a factor.

Try number 1:

a(x) = x^3 - 2x^2 - 4x + 3

a(3) = 3^3 - 2(3)^2 - 4(3) + 3

= 27 - 2(9) - 12 + 3

= 27 - 18 - 12 + 3

= 9 - 18 - 9

= 27 - 27

= 0

So a(x) has (x-3) is a factor of a(x)

The other 3 polynomials are solved in the same way.

Which absolute value represents a number less than |−0.14|
jasenka [17]

Answer:

See explanation

Step-by-step explanation:

The given absolute value is

| - 0.14|

When we simplify this we get:

| - 0.14|  = 0.14

Any absolute value expression whose value is less than 0.14 is a solution.

For instance :

| - 0.1|

|0.05|

| - 0.006|

are all less than the 0.14

Since you haven't provided the options, we can't provide an exact answer.

Please remember to post a complete question next time.

Which equation can be used to represent "three minus the difference of a number and one equals one-half of the difference of thr
Rina8888 [55]

Answer:

3 - (n - 1) = 1/2(3n - 4)

Step-by-step explanation:

We want to write three minus the difference of a number and one equals one-half of the difference of three times the same number and four as an equation.

Let the number be n.

The first part is: three minus the difference of a number and one:

3 - (n - 1)

The second part is: one-half of the difference of three times the same number and four:

1/2(3n - 4)

Now, let us equate the first and second parts:

3 - (n - 1) = 1/2(3n - 4)

PS: I really do not understand the options
