{24.NS.8} Steph places a point on a coordinate plane at (3, -2). She wants to place another point across the x-axis, and it must be 7 units away. Where will Steph place the other point?

We have been given that Steph places a point on a coordinate plane at (3, -2). She wants to place another point across the x-axis, and it must be 7 units away. We are asked to find the point, where Steph will place it.

Since the point will be across x-axis, so x-coordinate of of other point will be same that is 3.

Now we will use distance formula to find the coordinate of other point.

Square root will cancel out with square.

Therefore, the Steph will point the other point at .  

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
