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=-5.5Now 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 answerso, 5.5(2x) is 11x, and 5.5(-1) is 5.5. 5.5 satisfies the equation, therefore is the answer
