Reflection across the x-

B -> (-3, 9)

C -> (-3, 3)

D -> (3, 3)

E -> (3, 9)

Step-by-step explanation:

Hiya! My answer very well may be incorrect, considering that I have not seen this content in a fairly long while, but I assumed that it would be these coordinates. When reflecting across the x-axis, the goal is to flip it across the horizontal line. I assumed to leave the x coordinates be, considering how they would still be positioned along those lines, but I changed the y-coordinates to be opposite of what they were initially. By changing the y-coordinates, you can either move a figure up or down by taking the opposites of them, so I shifted the negatives to simply being positives. I hope this helped some in the very least!

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.
