Answer: 62
Step-by-step explanation:
You do 112-19-31 and then it equal = 62
 
        
             
        
        
        
You answer is 3 and here's why...
7x + 5 - 3x - 7 = 10 
First you must collect like terms
And that gives us
4x - 2 = 10
Next you must simplify by removing additives
4x - 2 + 2 = 10 + 2
4x = 12
Now you must divide
4x/4 = 12/4
x = 3

Answer:
The area of the trapezium is 
Step-by-step explanation:
Area of a trapezium:

This formula is valid if b1 and b2 are parallel and h is perpendicular to both.
Since the trapezium given in the problem satisfies those conditions, we use the formula with:
b1=15 cm
b2=7 cm
h=6.8 cm


The area of the trapezium is
