X^2 - 9x + 18
factors of 18: 1*18, 2*9, 3*6, 
the sums of the factors: 19, 11, 9
the positive 18 tells us both factors have the same sign, the negative 9 tells us they are both negative
(x - 3)(x - 6)
        
             
        
        
        
Answer:
The angle at B is the same as the angle at E so equate them to each other to find x
2x+4=40°
2x=40-4
2x=36
x=36/2=18

P=2L+2W
We know that L=26, W=21
so
Perimeter, P = 2(26)+2(21) = 52 + 42 = 94 feet
