The factors of the expression x^2 - 9x + 14 are (x - 7) and (x - 2)
<h3>How to factor the expression?</h3>
The expression is given as:
x^2 - 9x + 14
Expand
x^2 - 2x - 7x + 14
Factorize the expression
x(x - 2) - 7(x - 2)
Factor out x - 2 from the expression
(x - 7)(x - 2)'
Hence, the factorized expression of x^2 - 9x + 14 is (x - 7)(x - 2)'

Thank you for posting you question here at brainly. I hope the answer will help you.
T (z) = 2/3z over z - 1/2
T(3) = 2/2.5 = 4/5 or 0.8
T(1/2) is indeterminate, he reason being that the denominator becomes zero. Division by zero gives an indeterminate result.

=
1/3 ( because the limit as x approaches 0 of t/sin t = 1 ).
Angle RQN and angle RQS, because they will add up to 180 degrees
