<u>Let's first move everything, the constants and variables to one side</u>

    x^2-2=2x ⇒ x^2-2x-2=0

<u>The second form is in the general form of the quadratic equation</u>:

 ⇒ ax^2+bx+c = 0

  • a ⇒ 1
  • b ⇒ -2
  • c ⇒ -2

<u>To find the value of x, we can use the quadratic formula:</u>

  ⇒<em> look at the diagram attached</em>

<em />

<em>   </em>x = \frac{-b-\sqrt{b^2-4ac} }{2a} =\frac{2-\sqrt{(-2)^2-4(1)(-2)} }{2*1} =\frac{2-\sqrt{4+8} }{2} =\frac{2-\sqrt{12} }{2} =\frac{2-2\sqrt{3}}{2} =1-\sqrt{3}

  x = \frac{-b+\sqrt{b^2-4ac} }{2a} =\frac{2+\sqrt{(-2)^2-4(1)(-2)} }{2*1} =\frac{2+\sqrt{4+8} }{2} =\frac{2+\sqrt{12} }{2} =\frac{2+2\sqrt{3}}{2} =1+\sqrt{3}

Answer:

Solution 1: 1+1\sqrt{3}

Solution 2: 1-1\sqrt{3}

Step-by-step explanation:

x^2-2=2x

x^2-2x-2=0

Use quadratic equation.

(-b+-\sqrt{b^2-4ac})/2a

(2+-\sqrt{(-2)^2-4*1*-2})/2

(2+-\sqrt{(4+8}))/2

(2+-\sqrt{12})/2

Solution 1: (2+2\sqrt{3})/2=1+1\sqrt{3}

Solution 2: 1-1\sqrt{3}

A factory builds a new warehouse that is approximately 1.28x10^5 square feet. Later, they add on 1.13x10^3 more square feet for
alexdok [17]

Answer:

The correct answer is 1.2913 x 10^{5} square feet.

Step-by-step explanation:

A factory builds a new warehouse that is approximately 1.28 x 10^{5} square feet = 128,000 square feet.

Later, they add on 1.13 x 10^{3} square feet = 1,130 square feet more for offices.

Thus the total size of the new building is given by 128000 + 1130 = 129130 square feet = 1.2913 x 10^{5} square feet.

Thus in scientific notation the total area of the factory is 1.2913 x 10^{5} square feet.

A month of the year is chosen at random. What is the probability that the month starts with the letter J or the letter M?
Flauer [41]

Answer:

The probability that the month starts with the letter J or the letter M is 41.66%.

Step-by-step explanation:

Given that a month of the year is chosen at random, to determine what is the probability that the month starts with the letter J or the letter M, the following calculation must be performed:

January - March - May - June - July = 5 months

(5/12) x 100 = X

0.4166 x 100 = X

41.66 = X

Therefore, the probability that the month starts with the letter J or the letter M is 41.66%.
