Penny wrote the same number of holiday cards each day for 6 days, and she wrote a total of 42 cards. Graph the line relating the number of cards, y, to the number of days, x. Write the equation of the line that represents the relationship?

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"

what is the question?
