ExtremeBDS [4]
You can skip 4 in that equation and you'll be left with 2x+12=0, which gives you 2x=-12 and finally, x=-6

Simplify. 3 ft 23 in.
sleet_krkn [62]

Answer:

4 ft 11 inches

Step-by-step explanation:

Remember that 12 inches is 1 foot, so 24 inches is 2 feet. That means, 23 inches is 1 foot 11 inches. 11/12 is one inch gone from a foot, so 23/24 much be one inch gone from 2 feet.

Since you already have 3 feet, adding the 1 foot and 11 inches leaves you with 4 ft 11 inches as a result.

Choose either the SSS Postulate or the SAS Postulate and explain in your own words how you use that postulate to prove two trian
Veronika [31]
Let's use the SAS postulate! SAS means Side, Angle, Side. I would sometimes write this the other way and get in trouble, haha. 
It technically means if a triangle that has a congruent angle between two congruent sides, it means it is congruent. Here is a picture.

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.
