Final answer:
The given expression 5(−4t−5u) + 8u − 7(u + 2t) simplifies to −34t − 24u by distributing and combining like terms.
Step-by-step explanation:
To rewrite the expression in simplest terms you must distribute and combine like terms. The given expression is 5(−4t−5u) + 8u − 7(u + 2t). Let's distribute 5 into each term inside the first bracket, then −7 into the terms inside the second bracket:
- 5(−4t) = −20t
- 5(−5u) = −25u
- −7(u) = −7u
- −7(2t) = −14t
Now, combine all like terms:
- Combine t terms: −20t + −14t = −34t
- Combine u terms: −25u + 8u + −7u = −24u
The simplified expression is −34t − 24u.
