allochka39001 [22]

Answer:

$44,000

Step-by-step explanation:

The statement indicates that Sandra saves 9% of her salary and she saved $4,050 this year. That means that the 9% of her salary, x, is equal to $4,050. You can write the following:

x*0.09= 4,050

Now, you can isolate x to find her salary this year:

x=4,050/0.09= 45,000

Then, you have that this year salary was 1000 more than in her previous year. As you have found her salary for this year, you can subtract 1,000 from it to find her salary in the previous year:

45,000-1,000= 44,000

According to this, the answer is that her salary in the previous year was $44,000.

A perfect square trinomial can be represented by a square model with equivalent length and width. Which polynomial can be repres

lina2011 [118]

The correct answer is
$A) x^2 - 6x + 9$

In fact, this is a trinomial of the form $ax^2-bx+c$ , whose solutions are given by
$x_{1,2}= \frac{-b\pm \sqrt{b^2 -4ac} }{2a}$
Using this formula for the trinomial of the problem, we find:
$x1,2= \frac{6 \pm \sqrt{6^2-4\cdot 1\cdot 9}}{2} =3$
we see that this trinomial has two coincident solutions (x=3 with multiplicity 2). This means that it can be rewritten as a perfect square, in the following form:
 $(x-3)^2$
