A. 2x3=6 and 6x12=72 so 78 is greater than 36
6+72=79 which is less than 90
 
        
                    
             
        
        
        
Answer:
x = (y - b)/m
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. 
First subtract b from both sides: 
y = mx + b 
y (-b) = mx + b (-b)
y - b = mx
Next, divide m from both sides: 
(y - b)/m = (mx)/m
x = (y - b)/m
x = (y - b)/m is your answer.

Answer:
 336 ft²
Step-by-step explanation:
The rectangle is   13  ft long  and  8 width  that means we have  two walls 8* 9   and  two walls  13*9
Total walls area is
2*8*9 + 2*13*9   =   144  + 234   =  378 ft²
then we subtrac  , areas of door, closet and windows
3 * 6.5  =  19,5 ft²
3 * 6,5  =  19,5 ft²
2 * 1,5   =   3   ft²
                42 ft²
Then area to paint    378  -  42   =  336 ft²
