Find the sum and express it in simplest form.
(-73-y + 1) + (-7y3 - 6y)

-(7y^3+7y+36)

Step-by-step explanation:

(-73-y+1)+(-7y^3-6y)

-37+1-y-7y^3-6y

-36-y-6y-7y^3

-36-7y-7y^3

-7y^3-7y-36

-(7y^3+7y+36)

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

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
