To turn a percent into a fraction you just put the number over 100 and then simplify
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.

Answer:
5.5
Step-by-step explanation:
So, this is a simple factoring problem. The answer is 5.5(2x-1). So, heres how we get that answer.
So, factoring is basically breaking down the problem into smaller parts. So once we simplify the problem, we can factor it.
- Simplify by combining like terms: 5x+6x= 11x and -2.5-3=-5.5
- Now we have 11-5.5=?
- so, we need to have (2x-1) in our answer because the problem asks for that in the answer.
- We need to find a number that satisfies the equation and answer
- so, 5.5(2x) is 11x, and 5.5(-1) is 5.5.
- 5.5 satisfies the equation, therefore is the answer
