Answer:

Step-by-step explanation:
F(x)=2x^2+5x-16 for x=4

Answer:
X = 75
Step-by-step explanation:
Angle F and angle X are corresponding angles so they are congruent (equal)
Angle F and 105 form a straight line so they are supplementary angles, which means they add to 180
F+ 105 = 180
F = 180-105
F = 75
F = X = 75
The answer is 0, hope it helps lol
