Answer:
60
Step-by-step explanation:
given:
l = 10
b = 5
h = 2
to find:
2h(l + b)
substitute the given values of l , b and h
=2*2(10 + 5)
=4*15
=60
 
        
                    
             
        
        
        
Answer:
(-2,3,10,8)
Step-by-step explanation:
 eg
(x,y)=(domain,range) 
x components are domain and y components are range in the given set of ordered pairs
 
        
             
        
        
        
The probability is 4 out of 14
        
                    
             
        
        
        
Answer:
3x-22=80+x
3x-x=80+22
2x=102
x=51
Step-by-step explanation:
the exterior angle is (3x-22) and then is equal to sum of 80 and x 
and then we get 51
 
        
                    
             
        
        
        
Answer:
22x^2 -10xy + 12x
Step-by-step explanation:
To add and subtract polynomials, combine only like terms. When doing it vertically, stack polynomials and line up the same bases and exponents. Once this is done, simply add and subtract the coefficients. 
   10x^2 + 12xy + 4x
+ 12x^2 -22xy + 8x 
_________________
22x^2 -10xy + 12x
Here we added 10 + 12 = 22, 12 + -22 = -10 and 4 + 8 = 12.
