Answer:
Starts at 6:15
Note: An hour is 60 minutes.
So an hour after 6:15 is 7:15 and an hour after that is 8:15. Now just add another 10 minutes and you get 8:25.
So the film ended at 8:25.

Answer: x=80°
Explanation:
To find the exterior angle x we first need to find the last corner angle (a) of the triangle. The angles of triangles add up to 180° so we can use the formula: 25+55+a=180
Solving formula:
25+55+a=180
80+a=180
(Subtract 80 from both sides)
a=100°
Now that we know a=100 we can find the exterior angle. a+x=180 because the angles are on a straight line which equals 180°
a+x=180
100+x=180
(Subtract 100 from both sides)
x=80°

Answer:D
Step-by-step explanation:
you plug 4 in for x
f(4)=4^2+2(4)-3
=16+8-3
=24-3
=21
