16r^4t-6r^3t^2+4rt^2=
DochEvi [55]

Answer:

2rt(8r^3-3r^2t+2t)

Step-by-step explanation:

We have been given a polynomial 16r^4t-6r^3t^2+4rt^2 and we are supposed to simplify our polynomial.

We will use factoring to simplify our polynomial. Let us factor out the greatest common factor of all the terms.

We can see that 16, 6 and 4 has 2 as their greatest common factor.

The greatest common factor of r^4, r^3,r is r.

The greatest common factor of t, t^2, t^2 is t.

So the greatest common factor of the terms of our expression will be 2rt.

Let us factor out 2rt from our given polynomial.

2rt(8r^3-3r^2t+2t)

As we can not factor our expression more, therefore, we will get 2rt(8r^3-3r^2t+2t) after simplifying our polynomial.

6. (5 points) Graph using two intercepts; show your work in finding the intercepts. 6x - 3y = 18
Setler [38]

Answer:

Divide both sides by 18. The new coefficients will be the reciprocals of the intercepts:

6x-3y=18 \rightarrow \frac6{18}x - \frac3{18}y = 1 \rightarrow \frac x3-\frac y6 =1 The two intercepts are then 3 and -6.

(I know, dividing by 3 both sides of the equations would have made the whole process way easier).

Alternatively, plug x = 0 to find the y intercept and y=0 to find the x intercept. Either way the graph will look something like the one I'm sketching on paint.

Andy flipped a coin once and rolled a six-sided number cube numbered 1 through 6. The list below shows the possible outcomes whe
zhuklara [117]

Answer:

C. 1/4

Step-by-step explanation:

The probability of landing tails is 50%, since coins are two sided.

If a cube has 6 numbers, the probability of getting an even number is also 50% since 2,4,and 6 are even while 1,3, and 5 are odd.

The probability of getting both would be 25% (I multiplied 1/2 by 1/2)
