Answer:
8
Step-by-step explanation:
the pair of triangles is showing a dilations with a scale factor of 2
6/3=2 
so it gives us 4 as the before answer and 4x2=8 so x=8

Answer: D: 4.5
Step-by-step explanation:
So the Equation I used for this would be
6(2x+3) = 3(6x-3)
In Which the left is the Hexagon (The 6 is for the 6 Sides) and the right of the equation is the triangle (given the 3 for the 3 sides. In order to solve, we need to solve for x. Distribute the equation and your left with 
12x+18=18x-9
-12x            +9
27=6x
Divide to get X by itself
and your left with 
4.5 = x
Hope it helped.
 
        
             
        
        
        
Answer: 14 1/8
Step-by-step explanation: To add mixed numbers, first add the fractions. In this case, we have two fractions  and
 and  and these fractions have unlike denominators. We need to find a common denominator for both of these fractions to be able to add.

12 4/8 + 1 5/8 = 13 9/8
Notice that 9/8 is an improper fraction so we can change it to a mixed number.
9/8 = 1 1/8
13 + 1 and 1/8 = 14 1/8
