Answer:

169/4

Step-by-step explanation:

Take the coefficient of the x term.  Here it's -13.  Now halve that, obtaining -13/2.  Finally, square this result.  We get 169/4.  This is the desired number.

x^2 - 13x + 169/4 - 169/4 + 14 = 0

What is the measure of angle 3?
zheka24 [161]
Angles 6 and 8 add up to equal 180, so 2x - 5 + x + 5 = 180.  3x = 180 so x = 60.  Angle 3 is alternate interior to angle 6 which is 2(60) - 5 = 115, so angle 3 is also 115

  • Then, 7*5 is equivalent to 35.
  • So we have
  • 7n=35
  • In order to find the value of n, we need to divide both sides by 7:
  • n=5
