1 Option 7 (maximum 100 points) The length of a rectangle is one more than five times the width. A new rectangle is formed by decreasing the length by 10 cm and doubling the width. If the perimeter of the original rectangle is 23 more than half the perimeter of the new rectangle. Find the dimensions of the original rectangle.

yeah and

step-by-step explanation:

you know what it isnt great cheating

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
