Answer: 34y
Step-by-step explanation:
So first you have to round the nearest 2 to the nears 3 then you get 30 then you have to add 4 the add you variable.
 
        
             
        
        
        
Answer:
4
Step-by-step explanation:
look at the points that are intersected by the line. the first one is (2,8). put it in as Rise/Run to find the slope. you "rise" 8, and "run" 2 
so 8/2 is the slope. 
usually you need to simplify it.
8/2 = 4
 
        
             
        
        
        
Answer:
A.
Step-by-step explanation:
      In this series we see that an extra two dots (one on the top, one on the bottom of the same column) are being added on the left side.
-> It starts out at 3
-> Next it becomes 5, with the extra two on the left side
-> Now it is 7, with the last set of extra two also on the left side
      Using this logic, we can infer that the most likely answer will be A.
Have a nice day!

Answer:
b
Step-by-step explanation:
to prove if NP is tangent to MN
we could prove if NPM is a right triangle
By pythagorean theorem 
a^2+b^2=c^2
where a=MN=33
b=NP=180
c=MP=MQ+QP=152+33=185
so
33^2+180^2=185^2
but
1089+32400 is not equal to 34225
33489 is different from 34225
