Answer:
12x³+89x²-261x (?)
Step-by-step explanation:
For this equation, I am going to assume you want to find the value of the expression and you're multiplying all the values (since you can't find the value of x with this unless you had an equation).
(x)(4x-9)(3x+29)
(4x²-9x)(3x+29)
12x³+89x²-261x
40/16 = 24/x
16*24 = 384
x = 384 / 40
x =9.6
it cast a shadow 9.6 feet long
