Answer:
x = 9
Step-by-step explanation:
To solve these problems, you first set up an equation representing the information given.
6x = x² - 27
This turns into a quadratic equation which you need to factor out.
0 = x² - 6x - 27
You want to choose two numbers that multiply to -27, and add up to -6
0 = (x - 9)(x + 3)
If you're unfamiliar with factoring, you take the opposite sign of the number in the parentheses because it's a shortcut when setting it equal to 0.
x = 9, -3
Since it asks for the positive solution only, the answer is x = 9.
I hope this helps!
The only triangle with the base being bisected perpendicularly is an isosceles triangle or an equilateral triangle. Therefore,
Since the sides are equal, we can equate the expressions to get the equation:
is equal to .
Plug that in and you get which is . So, Option B is correct :D
