[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

a is a leg
b is another leg
c is the hypotenuse

Step-by-step explanation:

<u>Step 1: Identify</u>

<em>a</em> = x + 3

<em>b</em> = x

<em>c</em> = √117

<u>Step 2: Solve for </u><em><u>x</u></em>

Substitute [PT]: (x + 3)² + x² = (√117)²
Expand [FOIL]: x² + 6x + 9 + x² = (√117)²
Combine like terms: 2x² + 6x + 9 = (√117)²
Exponents: 2x² + 6x + 9 = 117
[SPE] Subtract 117 on both sides: 2x² + 6x - 108 = 0
Factor out GCF: 2(x² + 3x - 54) = 0
[DPE] Divide 2 on both sides: x² + 3x - 54 = 0
Factor Quadratic: (x - 6)(x + 9) = 0
Solve roots/solve <em>x</em>: x = -9, 6

Since we are dealing with positive values, we can disregard the negative root.

∴ x = 6

How many ways are there to select 7 countries in the United Nations to serve on a council if 3 is selected from a block of 54, 1

Strike441 [17]

Answer:

Total number of ways will be $=8.44727\times 10^{10}ways$

Step-by-step explanation:

We have to select 7 countries

3 countries selected from a block of 54

So number of ways of selecting these three countries $=^{54}c_3=\frac{54!}{3!51!}=\frac{54\times 53\times \times 52\times 51!}{6\times 51!}=24804ways$

Now 1 country is selected from 66 block

So number of ways to select 1 country = $=^{66}c_1=\frac{66!}{1!65!}=\frac{66\times \times 65!}{1\times 65!}=65ways$

Now next 3 country is selected from 69 country

So $=^{69}c_3=\frac{69!}{3!66!}=\frac{69\times68\times 67 \times 66!}{6\times 66!}=52394ways$

So total number of ways to select 7 countries = 24804×65×52394 $=8.44727\times 10^{10}ways$
