[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

Answer:
18245
Step-by-step explanation:
We have to use L.C.M,
L.C.M(20,24,32,38)
2|20,24,32,38
2| 10 ,12 ,16 ,19
2| 5 , 6 , 8 , 19
2| 5 , 3 , 4 , 19
2| 5 , 3 , 2 , 19
L.C.M = 2 x 2 x 2 x 2 x 2 x 2 x 5 x 3 x 19
= 18240
Now for each case remainder is 5,
So the number is 18240+5
=> 18245
