The penny size of a nail indicates the length of the nail. The penny size d is given by the literal equation d=4n−2, where n is
the length (in inches) of the nail. a. Solve the equation for n. n= Question 2 b. Use the equation from part (a) to find the lengths of nails with the following penny sizes: 3, 6, and 10. A 3-penny nail is inches. A 6-penny nail is inches. A 10-penny nail is inches.
I’m going to use Pythagorus theorem for his question. // firstly I would do 20^2 + 16^2 = 656 // we them square root that number, so the square root of 656 is 25.61, meaning the missing length is 25.6
