Hey there! 
⇒ Use the vertex as the middle letter, and the point from each side (<ABC or <CBA)
⇒ Use the vertex only (<B)
⇒ Use a number (<1)
- Classify angles according to their measure.
 
⇒ Acute angle: less than 90°
⇒ Right angle: exactly 90°
⇒ Obtuse angle: between 90° and 180°
⇒ Straight angle: exactly 180°
Thank you,
Eddie

There can be no negative in a sqrt 
so x+1 must be equal or greater then 0
x+1

 0
x 

 -1
so all answers must be greater then  or equal to -1
-1,0,1,2,3,4,5,6,7,8
(-1,infinity) is the domain
 
        
             
        
        
        
To get it into standard you need to simplify 
6y - 12 = -3x add 12 to both sides
6y = -3x + 12 add 3x to both sides
3x + 6y = 12 
And that is in standard which is A + B = C
        
             
        
        
        
Answer:
126.
Step-by-step explanation:
Each rectangle is a step. We'll start with the top one. This is simple: 6 times 3. 

The farthest left is 5 times 3. 

The crossed one is 6 times 5. 

The one to the right of the crossed one is 3 times 5, again.

The farthest right is 6 times 5, again.

The bottom one is 6 times 3, again.

Now, we add.
