ankoles [38]

Answer:

x = -4

x = 6

Step-by-step explanation:

x² - 2x -24 = 0

x² - 6x + 4x - 24 = 0

Solve for x. Round to the nearest hundredth.<br><br> x/24=0.2083
Harman [31]

Answer:

5 is your answer

Step-by-step explanation:

Isolate the x. Note the equal sign, what you do to one side, you do to the other. Multiply 24 to both sides

(x/24)(24) = (0.2083)(24)

x = (0.2083)(24)

Simplify

x = 4.9992

Round to the nearest hundredths place (underlined & bolded): 4.9<u>9</u>92

Look at the number to the right of the hundredths place. It is a 9. Because 9 is greater than 5, round up

4.9992 rounded to the nearest hundredth place = 5

5 is your answer
