Solve the inequality 4(a+6) > = 5(a+3)

(c) the diagram shows the first three shapes of a matchsticks arrangement. first shape = 3second shape = 5third shape = 7given m represents the number of matchstick used to arrange the n'th shape.(i) write a formula to represent the relation between m and n. express m as the subjectof the formula.(ii) 19 matchsticks are used to make the p'th shape. find the value of p.

Which will form a composite function?

For the feasibility region shown below find the maximum value of the function p=3x+2y
