#2 or B is not a function because it has 3 as X twice
Answer:
(5x +4y)^2
Step-by-step explanation:
The first and last terms are both perfect squares, and the middle term is twice the product of their roots. That means the trinomial is the perfect square trinomial ...
25x^2 +40xy +16y^2 = (5x +4y)^2
_____
It matches the pattern ...
a^2 +2ab +b^2 = (a +b)^2
Let's start with saying he earned 2766.79. He he also earns 9% of his sales.
9% of something is just .09 multiplied by that something. So if he earns 9% of 3743.37 plus the 2766.79, then we can say
y= 0.09 * 3743.37 + 2766.79
y = 3,103.69
The answer to your question is 21.5
X + 2 = 12
subtract both sides by 2
x = 10
