Answer: Start with the second expression. That factors easily into (8x-3)(8x+3).
Since 64x^2 + 48x + 9 has no negative signs, I'd bet that the common factor is (8x+3). Divide 64x^2 + 48x + 9 by that to verify.

Answer:
x = 24
Step-by-step explanation:
Since all the angles share a common vertex 'U' lying on a straight line QT.
Therefore, sum of all angles formed at U will be equal to 180°.
m∠RUQ + m∠RUS + m∠SUT = 180°
(2x - 4) + (3x + 5) + (2x + 11) = 180°
(2x + 3x + 2x) + (5 - 4 + 11) = 180
7x + 12 = 180
7x = 180 - 12
x =
x = 24
Therefore, value of x = 24
For an angle to be supplementary to another angle, they must be equal to 180. Angles 6, 10, 13, and 9 are all supplementary to angle 16. This is because angle 16 is supplementary to angle 9 by the <em>Same Side Interior Angles Theorem</em>, which makes it supplementary to angle 10 by the <em>Alternate Exterior Angles Theorem,</em> which is also congruent to angle 13 by the <em>Vertical Angles Theorem</em>, which is also supplementary to angle 6 by the <em>Alternate Exterior Angles Theorem.</em>
