Answer:

x² - 3x - 40 = 0

Step-by-step explanation:

(x + 5)(x - 8) = 0

x² + 5x - 8x - 40 = 0

x² - 3x - 40 = 0

Second = 8\ blocks east

Required

Determine the shortest possible distance

To better explain my solution, I've added an attachment that illustrates her movement.

Using the attachment as a point of reference, the shortest distance is calculated by calculating the length of the hypotenuse using Pythagoras theorem.

So, we have:

x^2 = 6^2 + 8^2

x^2 = 36 + 64

x^2 =100

Take positive square root of both sides

x = \sqrt{ 100

x = 10

Draw a line plot to correctly display the data 4,5,6,9,13,14,14,14,15 mean= median= mode= range=
ziro4ka [17]
Mean=10.4 since you add all the numbers which gives you 94 and divide by how many they are and that is 9
median=13 (middle number)
mode=14 constant seen number
range= 11 because 15 minus 4 is 11 (difference between your lowest and highest value
a line plot is another word for dot plot so just use 1 -20 and arrange the number
hope this helps
