Answer:
11 r + 4 n + 8 b + 10
Step-by-step explanation:
Simplify the following:
9 r + r + 7 b + 10 + b + r + 4 n
Grouping like terms, 9 r + r + 7 b + 10 + b + r + 4 n = (9 r + r + r) + 4 n + (7 b + b) + 10:
(9 r + r + r) + 4 n + (7 b + b) + 10
9 r + r + r = 11 r:
11 r + 4 n + (7 b + b) + 10
7 b + b = 8 b:
Answer: 11 r + 4 n + 8 b + 10
