Answer:
(1, 3)
Step-by-step explanation:
If quadrilateral ABCD is reflected across the line y = x, then the x- and y-coordinates get reversed. Since the coordinates of point D are (3, 1), then the coordinates of point D' are (1, 3).
Let the number be x
3x - 5 = 14
3x = 19
X = 6 1/3 or 6.333333...
Answer:
Area is the total surface covered by the shape and perimeter is the total length of the shape.
B={x|x is an even whole no less than 9}
Now
It is 20 because the 5 is in the ones place so the 2 has to be in the 10 place which makes it 20
