Question Category: Solving Quadratic Equations by Factoring Select the correct answer. Find the solution(s) for x in the equation below. x^2 - 9x - 20 = 0 A)x = 4; x = -5 B)x = -4; x = 5 C)x = 4; x = 5 D)x = -4; x = -5

Answers

Answer 1

Answer: x = 4; x = 5

Step-by-step explanation:

The directions specify to solve by factoring

x^2 - 9x + 20 = 0

To factor, find two numbers that add to -9 and multiply to 20

-5 and -4 work

-5 + (-4) = -9

-5 * -4 = 20

(x - 4)(x - 5) = 0

x = 4, x =5

Answers

Answer:

[tex]C=20+0.20N[/tex]

Step-by-step explanation:

Fixed monthly fee = $20

Amount charged per minute for long distance calls = $0.20

[tex]C[/tex] denotes total cost such that [tex]N[/tex] minutes are used for long distance calls.

Amount charged for [tex]N[/tex] minutes for long distance calls [tex]=0.20N[/tex]

Therefore, an equation for the total cost, C, when N minutes are used for long distance calls is [tex]C=20+0.20N[/tex]

Step-by-step explanation:

So, Pythagoras theorem can be used,

Hypotenuse ² = base ² + altitude ²

AB²=AC²+BC²

11²=AC²+4²

11²-4²=AC²

121-16=AC²

Root 105=AC

AC=10.2 cm

The length of AC is 10.25 cm

What is pythagorean theorem ?

If ΔABC is a right angle triangle, then

AB² = BC²+AC²

where AB = Hypotenuse, BC & AC are adjacent sides of the right angle

What is the required length of the side ?

Given, hypotenuse = AB = 11 cm

One of adjacent sides = BC = 4 cm

We have to find the length of AC.

Using pythagorean theorem,

AB² = BC²+AC²

⇒ AC² = AB² - BC²

⇒ AC² = 11²-4²

⇒ AC² = 121-16

⇒ AC = √105

⇒ AC = 10.25

So the length of AC = 10.25 cm
