PLEASE HELP IT'S URGENT :(
solve the following equations in the interval [0, 2π)

4cos²x + 4√3cosx + 3 = 0

2sinx - 3cotx = 0

The coordinates of point a right now is (-3,-1) you have to multiply these coordinates by a factor of 2 to get (-6,-2)

Volume is length times width times height so
20 times 8 times 30 which is 4,800
surface area is ph (p is perimeter of base), h is height.
so perimeter would be length+length+width+width so 20+20+8+8 which is 56. so multiply 56 times 30 which is 1680. hope this !
