Answer:
11.74b + 72.16
Step-by-step explanation:
In this question, we're going to simplify the expression.
Solve:
1.9b + 8.2(8.8 + 1.2b)
Use the distributive property.
1.9b + 72.16 + 9.84b
Combine like terms.
11.74b + 72.16
Since we can't simplify any further, 11.74b + 72.16 would be your answer.
If we multiply or divide both sides of an inequality by a negative number, you have to flip the inequality. Hope this helps :)
