X^2-2x-35=0 in quadratic equation

Mathematics
1 answer:
zaharov [31]3 years ago
5 0

Answer:

x = -5, 7

Step-by-step explanation:

Step 1: Write equation

x² - 2x - 35 = 0

Step 2: Solve for <em>x</em>

<u>Factor:</u> (x - 7)(x + 5) = 0

<u>Find roots:</u> x = -5, 7

Step 3: Check

<em>Plug in x to verify if it's a solution.</em>

(-5)² - 2(-5) - 35 = 0

25 + 10 - 35 = 0

35 - 35 = 0

0 = 0

7² - 2(7) - 35 = 0

49 - 14 - 35 = 0

35 - 35 = 0

0 = 0

There is 60 minutes in a hour so there is 50 people in 20 minutes. 
60 divide by 20= 3 20 times 3 equals to a hour so now you woud have to multiply the the people. 50 x 3= 150
In a hour there would be 150 people that ride the ferris wheel
