Answer:

$2x^{4}+x^{3}-x+2$

Step-by-step explanation:

To find which one is prime, let's try to factor them all. We can use the factoring by grouping method.

$x^{3}+3x^{2}-2x-6$

$x^{3}+3x^{2}$ and $-2x-6$

$x^{2}(x+3)$ and $-2(x+3)$

So this one is not prime, since you can still factor it.

$x^{3}+2x^{2}-3x-6$

$x^{3}+2x^{2}$ and $-3x-6$

$x^{2}(x-2)$ and $3(x-2)$

So this one is not prime, since you can still factor it.

$4x^{4}+4x^{2}-2x-2$

$4x^{4}+4x^{2}$ and $-2x-2$

$4x^{3}(x+1)$ and $-2(x+1)$

So this one is not prime, since you can still factor it.

$2x^{4}+x^{3}-x+2$

$2x^{4}+x^{3}$ and $-x+2$

$x^{3}(2x+1)$ and -x+2 cannot be further factored.

Therefore, $2x^{4}+x^{3}-x+2$ is a prime.

bixtya [17]

Answer:

The system of linear inequalities to model the situation is written as:

x + y ≥ 5..... Equation 1

4x + 10y ≤ 100..... Equation 2

Step-by-step explanation:

Let

The number is soil = x

The number of plants = y

You are buying plants and soil for your garden.

You want to buy at least 5 plants

At least = greater than or equal to with the inequality sign(≥)

Hence:

x + y ≥ 5..... Equation 1

The soil cost $4 per bag and the plants cost $10 each and can spend no more than $100.

No more than means Less than or equal to with the inequality sign( ≤ )

Hence:

$4 × x +$10 × y ≤ $100

= 4x + 10y ≤ 100..... Equation 2

Therefore, the system of linear inequalities to model the situation is written as:

x + y ≥ 5..... Equation 1

4x + 10y ≤ 100..... Equation 2
