9. The child is 10 years old, which leaves 37-10, which is 27. Divide 27 by three for the triplets. 27/3 is 9. The triplets are 9  years old
        
                    
             
        
        
        
Answer: it’s acute
Step-by-step explanation:
 
        
                    
             
        
        
        
=4m - 17+ 3m - 11
combine like terms
=(4m + 3m) + (-17 - 11)
=7m - 28
This can be factored/simplified by dividing everything by 7
=7(m - 4)
Hope this helps! :)

Answer:
1.23d = 52
Explanation:
If 52 meters is the water level after a 23% increase, then we can say that the initial depth d added to the 23% of d is equal to 52 meters. So:
d + 23%d = 52 meters
Since 23% is equivalent to 0.23, we get:
d + 0.23d = 52
Finally, adding the like terms, we get:
(1 + 0.23)d = 52
 1.23d = 52
So, the equation is:
1.23d = 52
