Question 1: find the distance between the points (1, 4) and (5, 1).
question 1 options:
7
5
25
√7

second option.

Step-by-step explanation:

You need to use the formula for calculate the distance between two points. This is:

Given the point (1, 4) and the point (5, 1), you can say that:

Now you must substitute these values into the formula.

The distance between the points (1, 4) and (5, 1) is the following:

This matches with the second option.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
