On a square gameboard that is divided into n rows of n squares each, k of these squares do not lie along the boundary of the gameboard. if k is one of the four numbers 10, 25, 34, or 52, what is a possible value for n?

7

Step-by-step explanation:

-if y is the width and the length of area k (see diagram), the difference between n and y is of 2 square sides, one at each side of y.

-therefore, assuming that n is a whole number and that there aren’t half squares, y must be a whole number too because, as previously said, n-y = 2 so y= n -2

-the only perfect square amongst the values for k you listed is 25, so taking n and y as whole numbers the only possible value for k is 25

-therefore y is 5 and n is 7 because n-y = 2 so y + 2 = n

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
