(18)Calculate the volume of this shape

108 cm cubed

Step-by-step explanation:

(1/2 of length•height)•width

(1/2 of 6•4)•9

(1/2 of 24) •9

12•9

108

X2 + 13x + 36 = 0

36 + 13x + x2 = 0

(9 + x)(4 + x) = 0

9 + -9 = 0 0 + x = 0 + -9 x = 0 + -9


 x^2 - 13x + 36 = 

(x - 9)(x - 4) = 0 

4² - 13(4) + 36 = 0 

16 - 52 + 36 = 0 

-36 + 36 = 0 
0 = 0 

9² - 13(9) + 36 = 0 

81 - 117 + 36 = 0 

-36 + 36 = 0 

0 = 0 

So the Answer Is x = 9 , 4
