Answer: 1. -5 2. 0 Step-by-step explanation: 1. Distribute the Negative Sign: =a−2a+−1(3a−(4a−5)) =a+−2a+−1(3a)+−1(−4a)+(−1)(5) =a+−2a+−3a+4a+−5 Combine Like Terms: =a+−2a+−3a+4a+−5 =(a+−2a+−3a+4a)+(−5) Answer: =−5 2. Distribute: =(13)(5)+(13)(−t)+−5+t+(−12)(5)+(−12)(−t) =65+−13t+−5+t+−60+12t Combine Like Terms: =65+−13t+−5+t+−60+12t =(−13t+t+12t)+(65+−5+−60) Answer: =0 Log in to Reply

Answer:1. -5

2. 0

Step-by-step explanation:Distribute the Negative Sign:1.=a−2a+−1(3a−(4a−5))

=a+−2a+−1(3a)+−1(−4a)+(−1)(5)

=a+−2a+−3a+4a+−5

Combine Like Terms:

=a+−2a+−3a+4a+−5

=(a+−2a+−3a+4a)+(−5)

Answer:

=−5

Distribute:2.=(13)(5)+(13)(−t)+−5+t+(−12)(5)+(−12)(−t)

=65+−13t+−5+t+−60+12t

Combine Like Terms:

=65+−13t+−5+t+−60+12t

=(−13t+t+12t)+(65+−5+−60)

Answer:

=0
