Expand and simplify: a) -3(x+2x-2) b) 4(x+2)+2x (5-1) Solve the following equations (find the value of the pronumeral): c) 4a 313 d) 1/3 + 10 = 2 e) The formula for the area of a triangle can be written as A = Dh where b is the base of the triangle and h is the height. Rearrange the formula to make "h" (height) the subject. Use this formula to find the height of a triangle that has an Area of 20 m and a base of 4 m.
