Answer:
a=24 0.5x24=12
Step-by-step explanation:
Let's call the left side of this tirangle y and downside z.
3² + 6² = y²
y² = 45
y² + z² = (3 + x)²
45 + z² = 9 + 6x + x²
x² + 6² = z²
45 + x² + 6² = 9 + 6x + x²
45 + x² + 36 = 9 + 6x + x²
45 + 36 - 9 = 6x
72 = 6x
x = 12

The solutions for the given quadratic equation are x = -1 and x = 3. So, option B is correct.
<h3>What are the solutions to an equation?</h3>
- The solutions to an equation are the one that satisfies the equation and makes it true.
- There are different methods to solve an equation and find its solutions.
- These solutions are also called zeros or roots of the equation.
<h3>Calculation:</h3>
The given equation is 4x² - 8x - 12 = 0
Since it is a quadratic equation, it has 2 roots or solutions.
On factorizing the given equation,
4x² - 8x - 12 = 0
⇒ 4x² - 12x + 4x -12 = 0
⇒ 4x(x - 3) + 4(x - 3) = 0
⇒ (4x + 4)(x - 3) = 0
According to the zero-product rule,
4x + 4 = 0 or x - 3 = 0
So, x = -4/4 = -1 or x = 3
Therefore, the solutions of the given equation are -1 and 3.
So, option B) x = -1 and x = 3 is correct.
