Every hour of driving uses 3 gallons of gas. use a table to find how many gallons of gas would be used if driving for 15 hours

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

its (2) option

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
