How do you simplify square roots.​

Mathematics
1 answer:
mixas84 [53]3 years ago
6 0

Answer:

Simplifying a square root just means factoring out any perfect squares from the radicand, moving them to the left of the radical symbol, and leaving the other factor inside the radical symbol. If the number is a perfect square, then the radical sign will disappear once you write down its root.

The diagonal of a television measures 27 inches.If the width is 22 inches, calculate its height to the nearest inch.
scoray [572]

Using the Pythagorean theorem, the height of the television is approximately 16 inches.

<h3>How to Apply the Pythagorean Theorem?</h3>

Given the following:

Length of the diagonal of the television = 27 inches

Width of the television = 22 inches.

Height of the television = ?

Using the Pythagorean theorem, we would find the height of the television as shown below:

Height of the television = √(27² - 22²)

Height of the television = √(729 - 484)

Height of the television = √245

Height of the television ≈ 16 inches

Thus, using the Pythagorean theorem, the height of the television is approximately 16 inches.

Find the slope of the line passing through the points (-2,3) a<br> and<br> (-9,6).
larisa [96]
<h3>Answer:   Slope = -3/7</h3>

===================================================

Apply the slope formula

m = (y2-y1)/(x2-x1)

m = (6-3)/(-9-(-2))

m = (6-3)/(-9+2)

m = 3/(-7)

m = -3/7

This means each time you go down 3 units, you go to the right 7 units.

Slope = rise/run = -3/7

rise = -3 and run = 7
