Answer:
x -7
Step-by-step explanation:
 (3x + 5) + (2x - 9) - (4x+3)
 3x + 5 + 2x - 9 -4x -3
x -7
 
        
                    
             
        
        
        
3^0 if zero is an exponent then the answer would be 1.

Answer:
(a) LM=12 units, LN=35 units, MN=37 units
(b)8 84 units
(c) 210 square units
Step-by-step explanation:
(a)
Since points L and M have same x coordinates, it means they are in the same plane. Also, since the Y coordinates of L and N are same, they also lie in the same plane
Length 
Length 
Length
Alternatively, since this is a right angle triangle, length MN is found using Pythagoras theorem where 

Therefore, the lengths LM=12 units, LN=35 units and MN=37 units
(b)
Perimeter is the distance all round the figure
P=LM+LN+MN=12 units+35 units+37 units=84 units
(c)
Area of a triangle is given by 0.5bh where b is base and h is height, in this case, b is LN=35 units and h=LM which is 12 units
Therefore, A=0.5*12*35= 210 square units
 
        
             
        
        
        
Answer:
The answer is 35
Step-by-step explanation:
If you do 15 divided by 3/7 you herb 35 you can check it by doing 3/7 of 35 and you get 15
