Ответ:
A = l x w
A = 16 x 4
A = 64
square:
A = l^2 OR l x l
64 = l^2
square root of 64 = square root of l^2
8 = l
the square has to have a side length of 8!
Ответ:
Vertex: (0, 12)
Direction: Upwards
Step-by-step explanation:
Easiest way to do this is to graph it. When you do so you should be able to see that your vertex is at (0, 12) and that the graph opens upwards (a is not negative, so no reflection over the x-axis).
