Answer:

  3(x−1)(x+5)/(2x(x−5))

Step-by-step explanation:

In general simplifying something like this requires you factor the various polynomials to see what factors may cancel.

  \dfrac{2x^2+2x-40}{4x^2-12x-16}\cdot\dfrac{3x^2-3}{x^2-5x}=\dfrac{2(x-4)(x+5)\cdot 3(x-1)(x+1)}{4(x-4)(x+1)\cdot x(x-5)}\\\\=\dfrac{3(x-1)(x+5)}{2x(x-5)}

Determine whether 52c2y4 is a monomial, binomial, trinomial, or other polynomial.
neonofarm [45]

Answer: Monomial.

Step-by-step explanation:

Ok, when we have a polynomial with only one term, this is a monomial.

If the polynomial has two terms, this is a binomial.

If the polynomial has 3 terms, this is a trinomial.

And so on.

In this particular case we have:

52*c^2*y^4

Where c and y may be variables.

We can see that here we have only one term, so this would be a monomial.

(notice that the number of variables does not affect the type of polynomial in this case, only the number of terms)

Answer:

  4%

Step-by-step explanation:

The amount of simple interest is given by ...

  I = Prt . . . . . amount P invested at annual rate r for t years

This can be solved for r:

  r = I/(Pt)

Using the given values, we find the rate to be ...

  r = 16/(200·2) = 16/400 = 4/100 = 4%

The annual interest rate is 4%.
