I CAN HELP YOUUUUUUUUUUUUUUUUUU!!!!!!!!!!!!!!!!!!1
lets distribute 7(x+3)
so 7(x)+7(3)
7x+21  or b
yay :)
        
                    
             
        
        
        
16-4=12
12x5=60
I'm putting together assumptions as this isn't really clear to me, I apologize.
        
             
        
        
        
Answer:
<h3> 
           44</h3>
Step-by-step explanation:
z -  some integer
2z - first given even integer (the smaller one)
2z+2  - even integer consecutive to 2z  (the larger one)
2(2z)    - twice the smaller number
2(2z) - 40    - the number 40 less than twice the smaller number
2(2z) - 40 = 2z + 2
4z - 40 = 2z + 2
2z = 42
  
2z+2 = 42+2 = 44
check:
2(2z)-40 = 2(42)-40 = 84-40 = 44
 
        
             
        
        
        
Answer:
Yes
Step-by-step explanation:
To make a triangle the 2 smaller sides must join together to become greater than or equal to the biggest side.
8+7=15
<em>Therefore,</em>
<em>side lengths 8, 7, and 15 do create a triangle.</em>

You multiply length times width or base times height.
