A = 225 in^2
W = 13.75
15x16 = 240 in^2
240/13.75 = 17.45 in
the mirror would not fit in a space that is 15 by 16 inches since its approximately 13 by 17 inches
a³ + b³ + c³ + 3abc = ( a + b + c)(a² + b² + c² + ab + bc + ca)
if a + b + c = 0. then a³ + b³ + c³ = 3abc
here a + b + c = 15 + (-9) + (-6)
a + b + c = 15 - 15
a + b + c = 0
so a³ + b³ + c³ = 3abc
15³ + (-9)³ + (-6)³ = 3(15)(-9)(-6)
= 2430
so the answer is 2430
I could explain it, but you have to ask me, other than that the answer is 5(x+7)(9x-4).
