The length of the unknown side is 16 meters

<h3>What is a right triangle?</h3>

A right triangle is a triangle that has one of its angles to be 90 degrees

The length of the unknown side is calculated using the following Pythagoras theorem.

20^2 = 12^2  +b^2

Evaluate the exponents

400 = 144  +b^2

Collect like terms

b^2 = 400 -144

Evaluate the like terms

b^2 = 256

Take the square root of both sides

b = 16

Hence, the length of the unknown side is 16 meters

Mars2501 [29]

Answer:

2. -x^{2} +3x+15

3. -x^{2} -x+9

Step-by-step explanation:

We add like terms together to simplify

2.  3x²-4x²= -x²     -2x+5x= 3x  6+9= 15  all equal to -x²+3x+15

Kisachek [45]

The chef will be able to prepare 3 servings of pasta because if you take one away from a whole number you have 9/10ths so you do that process again you have 2 servings but, you have 2 tenths left over so you add that to the 7 tenths.

Hope this helps :)
