Answer:
16x 
Step-by-step explanation:
2x^2(x+3)
2 times 2 = 4
4x(x+3)
4x + 12x =
16x
 
        
             
        
        
        
      If RS is the hypotenuse of the triangle RST and point T is in Quadrant 3, then point T must be the intersection of the lines: x = - 4 and y = - 5.
       Therefore, the coordinates of point T are ( x, y ) = ( - 4, - 5 ) 
       Answer:
       T ( - 4, - 5 )
        
                    
             
        
        
        
I'm not usually good at these questions but you can get a calculator that does weight multiplied by units.
so with your question it would be :
1.2 ounces x (48 units)
=  57.6 ounces
57.6 ounces
        
                    
             
        
        
        
2y is 2y, so it is equal to 17383.
IF you were looking for just y, than the answer is 17383/2 = y = 8691.5
        
                    
             
        
        
        
In order to get an 81 average, 
the student has to get 81x5=405
71+96+90+73+?=405
330+?=405
405-330=75
he needs to get an 75
