The triangle is isosceles, so the two marked side lengths are equal. Thus, 3x - 6 = x + 2, x = 4.
Answer:
The answer is
<h2>2( x + 3)(x - 5)</h2>
Step-by-step explanation:
To factor the expression
2x² - 4x - 30
<u>First factor 2 out of the expression</u>
That's
2( x² - 2x - 15)
<u>Next write - 2x as a difference</u>
2( x² + 3x - 5x - 15)
<u>Factor out x from the expression</u>
That's
2 [ x( x + 3) - 5x - 15 ]
<u>Factor out </u><u>-</u><u>5 from the expression</u>
2 [ x ( x + 3) - 5( x + 3) ]
<u>Factor out x+3 from the expression</u>
We have the final answer as
<h3>2( x + 3)(x - 5)</h3>

Step-by-step explanation:
Since they have to be synchronized, their parabolic equations must be equal to one another
3(t^2 + 9 - 6t) - (t^2 + 25 - 10t) - t + 2 = 0
2t^2 - 9t + 4
(2t - 1)(t - 4) = 0
t = 1/2, 4
From the options, the answer is 4
