Find the value of a In the isosceles triangle shown below.
8

A. x = √41

Step-by-step explanation:

We need to take one triangle, so we'll split it in half.

This makes the base 4.

Then we use Pythagorean Theorem:

5^2 + 4^2 = x^2

25 + 16 = x^2

41 = x^2

√41 = x

$X = $12y

Step-by-step explanation:

In this question, we are asked to give an expression to represent the amount of money charged to a man who stayed in a motel for a particular number of days.

Firstly, we need to know the amount of money charged per day. This is visible from

the question and it is equal to $y.

Secondly, the number of days/night stayed is 12 days. This means that the amount of money he was charged is 12 * y = $12y

Since the amount of money charged is equal to $x, the amount to pay can be expressed in terms of y and x to be

$X = $12y
