Replace x by 4
F(4)= 19(4)+10
F(4)=76+10
F(4)= 86
Hope this helps!!
Answer:
C
Step-by-step explanation:
1)Non- zeros (1,2,3,....) are always significant.
2)Captive zeros are significant too( zeros between non- zeros ).

Such this question we have decimal point so we count them
Answer:
In the screenshot, since it won't let me do fraction form.
Step-by-step explanation:
There are 16 possible hands.
Choosing 3 aces from 4 possible is expressed by:

Choosing 1 queen from 4 possible is expressed by:

This gives us 4*4 = 16 possible hands.
Angle 1 = 130°
Angle 2 = 124°
Angle 3 = 56°
Angle 4 = 52°
Angle 5 = 72°
Angle 6 = 94°
I primarily used the triangles to get my answers. Remember the angles in a triangle add up to 180°.
