The total amount of money he only made is calculated by
the formula:
amount made = 15,200 – 912
amount made = 14,288
 
Therefore the percentage commission was:
% commission = 912 / 14,288 * 100% 
<span>% commission = 6.38 %</span>
 
        
             
        
        
        
<span>10r^2 − 11r − 6 = (2r - 3)(5r +2)
so
A = </span>(2r - 3)(5r +2)<span>
as you know A =  L * W
if width = </span>(2r - 3) then length = (5r +2)
answer
length = (5r +2)
        
             
        
        
        
Answer:
x = -4 and x = 5
Step-by-step explanation:
Since  and
 and  both equal to y, we know that the expressions equal to each other. We can write a new equation base on that.
 both equal to y, we know that the expressions equal to each other. We can write a new equation base on that.

Now we solve the equation.






 
        
             
        
        
        
Answer:
m<Q = 133°
Step-by-step explanation:
From the question given above, the following data were obtained:
m<P = (x + 13)°
m<Q = (10x + 13)°
m<R = (2x – 2)°
m<Q =?
Next, we shall determine the value of x. This can be obtained as follow:
m<P + m<Q + m<R = 180 (sum of angles in a triangle)
(x + 13)° + (10x + 13)° + (2x – 2)° = 180
x + 13 + 10x + 13 + 2x – 2 = 180
x + 10x + 2x + 13 + 13 – 2 = 180
13x + 24 = 180
Collect like terms 
13x = 180 – 24
13x = 156
Divide both side by 13
x = 156 / 13
x = 12
Finally, we shall determine m<Q. This can be obtained as follow:
m<Q = (10x + 13)°
x = 12
m<Q = 10(12) + 13
m<Q = 120 + 13
m<Q = 133°
