Solve the equation by factoring. 18a2=8

First step is to set it equal to 0, so subtract 8 from both sides.

18a^2-8 =0

Now take out the GCF

2(9a^2-4) = 0

Now both 9 and 4 are squares, so we can do the following:

2(3a+2)(3a-2) = 0

Therefore, a = -2/3 and 2/3

I hope this Helps!

Construct the perpendicular bisector of segment XY.

Step-by-step explanation:

If we can draw a circle through all the vertices of a triangle then the circle is called the circumscribed circle of the triangle.

The center of the circumscribed circle is the point through which the perpendicular bisector of each side of the triangle pass.

Therefore, the first step to construct a circumscribed circle of a triangle XYZ is to find its center and to get the center we have to construct the perpendicular bisector of segment XY. (Answer)
