10m + 80 = P 
where every month he gets 10, and for 6 months, he now has 60
plus the 80 he already has 
so (10 * 6 ) + 80 = 140
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
 x =(7-√193)/18=-0.383

Answer:
B	6 centimeters
Step-by-step explanation:
 y = x + 2
 2x + 3y = 36 
substitute y = x+2  into the second equation
2x + 3 (x+2) = 36
distribute
2x + 3x+ 3*2 = 36
combine like terms
5x+6 = 36
subtract 6 from each side
5x +6-6 = 36 -6
5x = 30
divide by 5
5x/5 = 30/5
x = 6
the short side is x =6
the longer side is 
y= x+2
y = 6+2
y =8
