Answer: 2a^2+22a+−1
Step-by-step explanation:
Let's simplify step-by-step.
2a^2−5a+(9)(3)a−1
=2a^2+−5a+27a+−1
Combine Like Terms:
=2a^2+−5a+27a+−1
=(2a^2)+(−5a+27a)+(−1)
=2a^2+22a+−1

Noa started at – 400 meters below sea level.
<u>Step-by-step explanation:</u>
We have , Noa drove from the Dead Sea up to Jerusalem, and her altitude increased at a constant rate of 740 meters per hour. When she arrived in Jerusalem after 1.5, point, 5 hours of driving, her altitude was 710 meters above sea level. We need to find the initial height from sea level . Let's find out:
Let N(t) be Noa’s altitude to sea level and time t .
. where h is initial height we need to find.
She was 710 meters above sea level after 1.5 hours. So,
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , Noa started at – 400 meters below sea level.
