Answer:
Step-by-step explanation:
Theorem: A line drawn from the center perpendicular to the chord bisects the chord.
By the Theorem above, Point E and F bisects CD and AB into 6 Units each as seen in the diagram.
Therefore:
|FB|=6 Units
In Right Triangle OED, applying Pythagoras Theorem
Therefore:
Answer:
x(2x + 3) + (x - 3) (x - 4) = 3x²- 4x + 12
Step-by-step explanation:
<em>Expand:</em>
x(2x + 3): 2x² + 3x
2x² + 3x + (x - 3) (x - 4)
<em>Expand</em>:
(x - 3) (x - 4): x²- 7x + 12
2x² + 3x + x²- 7x + 12
<em>Simplify:</em>
2x² + 3x + x² - 7x + 12: 3x² - 4x + 12
= 3x² - 4x +12
<u><em>Both the statement and its contrapositive are true. </em></u>A right angle will always be 90 degrees, so both are true.
