Answer:
15.4z - 12
Step-by-step explanation:
We have to simplify the expression 7.4z−5(−1.6z+2.4)
Distribute -5 over the parenthesis
7.4z + 8z - 12
Now, 7.4z and 8z are like term. So we can combine these two.
On combining the terms, we get
15.4z - 12
Therefore, the simplified expression is 15.4z - 12
