Juanita has 3 rectangular cards that are 5 inches by 7 inches. How can she arrange the​ cards, without​ overlapping, to make one larger polygon with the smallest possible​ perimeter? How will the area of the polygon compare to the combined area of the 3 ​cards?

i think 1: 2

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

once you solve it out the value of x is 13
