Given that the volume of a rectangular prism is given by the formula v = lwh, what is the value of v if l = 7 cm, w = 5 cm, and h = 4 cm?

140cm3

Step-by-step explanation:

v=lwh=7·5·4=140cm^3

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
