Let x = the number. 
"increased by" tells you we are adding. 
"twice a number" tells you 2 times a number. 
16 + 2x = - 24
Subtract 16 from both sides so that we have the variable on one sides and the constants on the other. 
2x = - 24 - 16
2x = - 40
Divide by 2 to isolate the variable. 
x = - 40/2 = - 20
Your solution is - 20. 
To check your answer, plug in. 
16 + 2(-20) = - 24
16 - 40 = - 24
- 24 = - 24

Answer:
√100 = 10, √36 = 6, √225 = 15
Step-by-step explanation:
100 can be made by 10^2 (10 x 10), 36 has factors of 6 and can be made by 6^2, and 225 can be made by 15^2.
 
        
                    
             
        
        
        
It would be C. You would multiply X by 2 and then subtract 15.
