Answer:
The value of expression 2x + 6 at x = 4 is 14 .
Option (C) is correct .
Step-by-step explanation:
As given the expression in the question be as follow .
= 2x + 6
Put x = 4 in the above equation
= 2 × 4 + 6
Simplify the above
= 8 + 6
= 14
Therefore the value of expression 2x + 6 at x = 4 is 14 .
Option (C) is correct .
Since V = (4/3) * pi * R^3
If R is halved, V' will reduce by a ratio of (1/2)^3 = 1/8
So V' = (1/8)V

Answer:
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
