Answer:
she should place 76 tiles along 1 side of the square
Step-by-step explanation:
300 = 4n - 4
answer will leave u with n=76
(f - g)(x) = f(x) - g(x)
(f - g)(x) = ( f(x) ) - ( g(x) )
(f - g)(x) = (4x^2 - 6) - ( x^2 - 4x - 8)
(f - g)(x) = 4x^2 - 6 - x^2 + 4x + 8
(f - g)(x) = (4x^2-x^2) + 4x + (-6+8)
(f - g)(x) = 3x^2 + 4x + 2
