Step-by-step explanation:

x^2 + y^2 = r^2 --> r =\sqrt{(-4)^2 + 5^2} =\sqrt{41}

cos = x /r = -4 /\sqrt{41}

sin = y /r = 5/\sqrt{41}

tan = sin /cos = -5 /4

Is -(3x + 5)^2 a perfect trinomial? Why or why not?
attashe74 [19]

The given equation-(3x + 5)^2 is not a perfect trinomial because it is not obtained through the multiplication of a binomial.

<h3>What is a perfect trinomial?</h3>

A perfect square trinomial is takes the algebraic expression form ax^2 +bx + c, where the square root of the first term and the third term is the equation to the second term.

Given that:

-(3x + 5)^2

Open brackets

= - (9x +30x + 55)

Multiply through by (-)

= -9x^2 - 30x - 55

Therefore, we can conclude that the given equation-(3x + 5)^2 is not a perfect trinomial because it is not obtained through the multiplication of a binomial. i.e. the multiplication of the square root of the first and the third term did not result in the 2nd term.
