Simplify the following.(2x-y)(x+2y)​

Step-by-step explanation:

When given the following problem;

Distribute, multiply every number in one of the parenthesis by every number in the other;

Simplify,

Therefore, the final answer is;

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
