Need help plsss ty

the answer is the third one. I calculated the work on my phone and also did it on paper to check and make sure my work was correct!

Step-by-step explanation:

option 4

Step-by-step explanation:

let the side of the square be s , then

length of rectangle = s + 14 and width = s - 4

Since the areas are equal then

s² = (s + 14)(s - 4) ← distribute using FOIL

s² = s² + 10s - 56 ( subtract s² - 56 from both sides )

56 = 10s ( divide both sides by 10 )

5.6 = s

Then

area of square = s² = 5.6² = 31.36 cm²

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'.
