The equation that fits the standard form of a Quadratic equation is 2(x + 5)² + 8x + 5 + 6 = 0 which can be re-written as 2x² + 28x + 61 = 0.
<h3>What is a Quadratic Equation?</h3>
Quadratic equation is simply an algebraic expression of the second degree in x. Quadratic equation in its standard form is;
ax² + bx + c = 0
Where x is the unknown
From the given data, we check which of them fits the standard form of a quadratic equation.
- 2(x + 5)² + 8x + 5+ 6 = 0
2(x + 5)² + 8x + 5 + 6 = 0
2( (x(x+5) + 5(x+5) ) + 8x + 5 + 6 = 0
2( x² + 5x + 5x + 25 ) + 8x + 5 + 6 = 0
2( x² + 10x + 25 ) + 8x + 5 + 6 = 0
2x² + 20x + 50 + 8x + 5 + 6 = 0
2x² + 20x + 8x + 50 + 5 + 6 = 0
2x² + 28x + 61 = 0
Therefore, the equation that fits the standard form of a Quadratic equation is 2(x + 5)² + 8x + 5 + 6 = 0 which can be re-written as 2x² + 28x + 61 = 0.

Answer: B. Benford's law
Step-by-step explanation:
Benford's law created by Simon Newcomb is used to determine the number of times or percentage that a digit will occur in a series or collection of numbers
Answer:
answer: 9
Step-by-step explanation:
Assuming this is the Pythagorean theorem the formula is a²+ b² = c² so we arent given a but we are given c so we have to work backwards c = 15 and 15 × 15 = 225 12 × 12 = 144 225 - 144 = 81 so Now we just have to figure out what multiplied by itself equals 81 therefore 9 is our answer because 9 × 9 = 81 Hope that helps!
