There are two triangles that are 15cm in height and 10cm in width so you do 15 times 10 which is 150 then divided it by 2 because it a triangle to get 75 then because there is 2 you then multiply it by 2 again and you get 150
        
             
        
        
        
Answer:
<em>B) -7x + 7y = -49</em>
Step-by-step explanation:
This is a y=x plot/line shifted by 7 units.
This can also be verified plugging in the values of x=0,y=-7 and x=7,y=0. The only equation which satisfies these points in Equation B. These points have been chosen as they're the intercepts of this plot.
 
        
                    
             
        
        
        
1/15=144/x
Cross multiply 
X=2,160
Gymnasium=2,160 ft2
        
                    
             
        
        
        
Hypotenuse or C (x) can be found with the equation

After solving you get about 6.32
6.32 about the same as 
 
 
        
        
        
First, we are going to find the painted area of his house. We know that the total area he needs to paint is 4000 square meters, so 4000 is the area of this house. Now, to find the 62.5% of that area, we are going to multiply it by 

:
Painted area= 

Now, to find <span>rate, in square feet per hour, we are going to divide the painted area by the number of hours: 
Rate=</span>

We can conclude that Kyler paints at a rate of 
434.78 square feet per hour.
