Answer:
I'd need to see more, but because they are the same number just positive and negative they'd be on opposite ends of zero
The true statement about the set of quadrilaterals in the coordinate plane is B. Because quadrilateral ABCD can be reflected across the x -axis, then rotated 90° counterclockwise about the origin, and then dilated about the origin by a scale factor of 2 to obtain quadrilateral A'B'C'D' , then quadrilateral ABCD is similar to quadrilateral A'B'C'D'.
<h3>What is a quadrilateral?</h3>
A quadrilateral is a polygon having four sides, four angles, and four vertices.
In this case, because quadrilateral ABCD can be reflected across the x -axis, then rotated 90° counterclockwise about the origin, and then dilated about the origin by a scale factor of 2 to obtain quadrilateral A'B'C'D' , then quadrilateral ABCD is similar to quadrilateral A'B'C'D'.

Answer:
72.25
Step-by-step explanation:
Triangles are 1/2(base x height), or (base x height) / 2.
17 x 8.5 = 144.5
144.5 / 2 = 72.25
The first one is 12,and the second 24....dont worry about marking me as brainliest just thank me lol
Subtract the exponents when the base number is the same.
2 - 7 = -5
So 9^-5 or 1/9^5.
