The statement "A real world situation, would be there is a total of 10 bowling shelves that contain bowling bowls. The first shelf contains 5 bowling balls, and each row has 3 more bowling balls. So in the 7th row there would be 28 bowling balls" is not a correct statement. The 7th row will actually have 23 bowling balls.

(m+11n)^2=(m+11n)(m+11n)=m^2+11mn+11mn+121n^2=m^2+22mn×121n^2 for example; use foil: (a+b)(a+b)first. a^2outside. abinside. ablast. b^2
