Pls i need help now asap math is starting soon and ending also plsss help me plsss guys

What is 1/2 x (6 x 4)+3 + 2 show your work

Solve the triangle. a = 21°, c = 105°, c = 5

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
