Answer:
Because if they werent the messerue ments would be screwed and u would not be able to answer some questions
Step-by-step explanation:
also it makes a right triangle if equal
 
        
             
        
        
        
36m+27+6m=0### 30m=27###m=9/10
        
             
        
        
        
So first of all they are similar because they are in the same degree and the top and bottom of each one is equal, and so are the left and right. You need to set up a proportion of 10:3.12 and 5:1.2 because those are the sides that match up. They match because if you rotate the second figure to the right it would match the figure on the right. The only available answer then out of 10:3.12 and 5.12 is letter A. Hope this helps comment if you need any more help or it’s confusing.
        
             
        
        
        
Answer:

Step-by-step explanation:
hello

so to know the maximum to y we can check the maximum of 
f(x)=
f is derivable and f'(x)=6-2x
f'(x)=0 <=> x = 3
so the maximum is reached for x = 3
f(3)=18-9=9
and then 

to be rigorous, we can write the variation table of y to show that there is only one maximum 
hope this helps
 
        
             
        
        
        
Answer:What number must be multiplied by 3 to obtain 15? ... Example 11 A student solved the equation 5x - 3 = 4x + 2 and found an answer of x = 6. ... Example 12 3x = 6 and 2x + 1 = 5 are equivalent because in both cases x = 2 is a solution. ... + 3x = 7x + 2 - 4x can be changed to a simple equation x = 3, and the equation x = 3 is .
