To simplify the given expression, we can distribute the 3 to both terms inside the parentheses:
3(-4.5b - 2.1) - (6b + 0.6) = -13.5b - 6.3 - (6b + 0.6)
Then, we can remove the parentheses and combine like terms:
-13.5b - 6.3 - (6b + 0.6) = -13.5b - 6.3 - 6b - 0.6
Combine like terms:
= (-13.5b - 6b) + (-6.3 - 0.6)
= -19.5b - 6.9
Therefore, the expression that is equivalent to 3(-4.5b - 2.1) - (6b + 0.6) is -19.5b - 6.9.
Which expression is equivalent to 3(−4.5b − 2.1) − (6b + 0.6)?
19.5b + 1.5
−19.5b − 1.5
−19.5b − 6.9
19.5b − 6.9
