If r 9 b 5 and g -6 what does (r plus b - g)(b plus g) equal?

First, substitute the values: ( r = 9 ), ( b = 5 ), and ( g = -6 ). Calculating ( (r + b - g) ) gives ( (9 + 5 - (-6)) = 9 + 5 + 6 = 20 ). Next, calculate ( (b + g) ) as ( (5 + (-6)) = 5 - 6 = -1 ). Finally, multiply the results: ( 20 \times (-1) = -20 ).
