Find the area of a regular hexagon with apothem 2 square root 3mm. round to the nearest whole number.

a 42mm^2
b 66mm^2
c 83mm^2
d 91mm^2

If f(x) = 4x – 3 and g(x) = 8x + 2, find each function value a. f[g(3)] b. g[f(5)] c. g{f[g(-4)]}

Which of the expressions (on the photo document i inserted) together represent all solutions to the following equation? 8cos(12x)+4=-4 *the answer should be in degrees.* > i would like for someone to explain the process to find the solutions for this.

What is the value of x when x + 7 = 21?
