What is the correct order of operations for simplifying the expression (x+3)^2-(x^2+9)/2x^2

Answers

Answer with explanation:

The correct order of simplifying the expression is:

1. Opening the bracket Using Identity

2. Adding and Subtracting Like terms

The given expression is

$=((x+3)^2-(x^2+9))/(2x^2)\n\n=(x^2+6 x+9-x^2-9)/(2x^2)\n\n=(6x)/(2x^2)\n\n=(3)/(x)\n\n \text{Used the identity and law of indices}\n\n(a+b)^2=a^2+2 a b+b^2\n\n (x^a)/(x^b)=x^(a-b)$

$((x+3)^2-(x^2+9))/(2x^2)\n\nuse\ (a+b)^2=a^2+2ab+b^2\n\n=(x^2+2\cdot x\cdot3+3^2-x^2-9)/(2x^2)=(x^2-x^2+6x+9-9)/(2x^2)\n\n=(6x)/(2x^2)=(3)/(x)$

Amir owns and operates a clothing store. He sells a shirt for $59.95. He Originally bought the shirt for $40.50. What is the buying price as a percent of his selling price?

Answers

Answer:

32.45%

Step-by-step explanation:

To find the buying price as a percent of the selling price, we need to calculate the profit margin as a decimal first:

Profit margin = Selling price - Buying price

Profit margin = $59.95 - $40.50

Profit margin = $19.45

Now we can find the percent by dividing the profit margin by the selling price and multiplying by 100:

Percent = (Profit margin ÷ Selling price) x 100

Percent = ($19.45 / $59.95) x 100

Percent = 32.45%

Therefore, the buying price is 32.45% of the selling price.

y - y1 = m (x + x1)

Solve for m bgg subtracting the y's and dividing them by the difference of the 2 x's.

-31 - 35 = -66
-6 - 5 = -11

Divide the two to get 6.

Use the first point (as instructed) and plug it into the equation.

y - 35 = 6 (x - 5)

y + [-35] = [6] (x + [-5])
