Answer:

= 2(1 - 2h)

Step-by-step explanation:

Given that:

=3(2−0.9h)+(−1.3h−4)

Simplifying:

=(6 - 2.7h) + (-1.3h - 4)

Removing brackets

=6 - 2.7h -1.3h - 4

Adding like terms (h terms and constants)

= 2 - 4h

We can take 2 common as:

= 2(1 - 2h)       Required sum

I hope it will help you!
