Answer:

The answer is $33

Step-by-step explanation:

<h3><u>Given</u>;</h3>
  • A dance instructor earns $30 for teaching a class.
  • The instructor earns a 10% raise.

Here,

$30 × 10 ÷ 100 = 300/100 = $3

Here, we know the raised amount.

So,

$30 + $3 = $33

Thus, the instructor get paid for teaching a class is $33

In rectangle QRST, QS = x2 + 6x, and RT = 8x + 3. Find the length of QS.
valentina_108 [34]

The length of QS is 27 units.

<u>Step-by-step explanation:</u>

In the given rectangle QRST QS and RT are the diagonals. In a triangle, the opposite sides are equal and parallel. This implies that the diagonals of a rectangle are equal.

QS=RT \ QS=x^2+6x

RT=8x+3

x^2+6x=8x+3

x^2+6x-8x-3=0

x^2-2x-3=0

We have obtained a quadratic equation here and solving this gives the possible values of QS.This can be solved using quadratic formula

x=(-b\pm \sqrt{(b^2-4ac))}/2a

The quadratic equation is of the form ax^2+bxl+c=0  

here a=1 b=-2 c=-3  

x=(-b\pm \sqrt{(b^2-4ac))}/2a

x=x=(2 \pm \sqrt{ (-2^2-4 \times 1 \times -3))}/(2 \times 1)

x=(2 \pm \sqrt{(4+12))} /2 or  

x=(2 \pm \sqrt{16)}/2 =(2\pm 4)/2 \ \ \ \ x=(2+4)/2=3 \ \ \ \ or  \ \ \ x=(2-4)/2=-1

putting x=3 QS=x^2+6x

=3^2+6 \times 3=9+18=27

putting x=-1

QS=(-1)^2+6 \times -1=1-6=-5

Since a length can have only positive values QS=27 units.

Step-by-step explanation:

-4 is really  -1 * 4

-4² = -1 * 4²

-4² = -1 * 16

-4² = -16

Use parenthesis  to square

(-1 * 4)² = (-4)²

(-4)² = 16
