Find the length of the missing side. the triangle not drawn to scale. (Image attached)
3241004551 [841]

Answer: 8

Step-by-step explanation:

 The triangle shown in the image attached is a right triangle.

Therefore, to calculate the missing lenght of the triangle you can apply the Pythagorean Theorem, which is shown below:

a^2=b^2+c^2

Where <em>a</em> is the hypotenuse and <em>b</em> and <em>c</em> are the legs.

The problem gives you the value of the hypotenuse and the value of one leg. Therefore, you must solve for the other leg from a^2=b^2+c^2, as following:

17^2=15^2+c^2\\c=\sqrt{17^2-15^2}\\c=8

Therefore, the lenght of the missing side is: 8

Dmitrij [34]

Answer:

9x+7

Step-by-step explanation:

This is because you combine like terms:

5x and 4x contain the same variable and amount of variables so you can combine them making 9x. You are then left with two numbers 5, and 2 they aren't attached to any variables and are in common in that way so you combine them too! This makes them 7, lastly you make it into an expression so you can't combine 9x and 7 so you leave it as 9x+7!!!
