What is the positive solution to the equation 0 = –x2 + 2x + 1? Quadratic formula: x = StartFraction negative b plus or minus St
katrin [286]

Answer:

x = 2 + √2

x = 2 - √2

Step-by-step explanation:

- x² + 2x + 1 = 0

x² - 2x - 1 = 0

Here,

a = <em>1</em>

b = <em>- 2</em>

c = <em>- 1</em>

Now,

Discriminant

D = b² - 4ac

= (-2)² - 4(1)(-1)

= 4 + 4

= 8

=2√2 > 0

<em><u>Real and </u></em><em><u>D</u></em><em><u>istinct roots </u></em>

x = - b +- √b² - 4ac/2a

= - (-2) +- √ = (-2)² - 4(1)(-1)/2(1)

= 2 +- √4 + 4/2

= 2 +- √8/2

= 2 +- 2√2/2

= 2 +- √2

x = 2 + √2 or x = 2 - √2

Q9. 

This question can't be answered. It is necessary to get the dimensions of the figure.

Q10. 

Let's find a conclusion having statements step by step.

a) If 3 cans of soup cost a total of $0.85, then 1 can of soup costs:

\frac{\$0.85}{3}

b) If I get n cans of soup the equation I need to use is multiply the previous equation by n:

(\frac{\$0.85}{3})n

The conclusion is: G. Multiplying n by the cost of 1 can.

Q11. 

Let's find a conclusion having statements step by step.

a) The company charges $40 to hook a vehicle, so this is a constant variable. Then:

c = 40$

b) There is a second statement that states that for each mile the vehicle is towed the cost increases $1.70, so:

c = $40 + 1.70m

So, the answer is B.
