Answer:
a) -3
b) 117
c) 100
Step-by-step explanation:
(a) 2(1)²-5(1)
1²= 1
2×1= 2
2-5= -3
(b) 2(9)²-5(9)
9²= 81
81×2= 162
162-45= 117
(c) 2(4)²-5(4) +2(8)²-5(4)
4²=16
16×2= 32
32-20= 12
8²=64
64×2= 128
128-40= 88
88+12= 100
hope it helps!
So, to do this, all you need to do is add up all the values, and then, with that number, divide by how many values are given.
150+165+165= 480
480/3= 160
Answer:
3+3 is 6.
Have a great day and stay safe! :) :D :3
Answer:
Suzi's elevation in the hike is 37 feet.
Step-by-step explanation:
We are given the following in the question:
Position of Suzi in the starting of hike = 200 feet below sea level
= -200 feet
The negative sign shows below sea level.
Position of Suzi in the end of hike = -163 feet
Change in elevation from the beginning of Suzi's hike to the end of the hike
= Position of Suzi in the end of hike - Position of Suzi in the starting of hike

Thus, Suzi's elevation in the hike is 37 feet.
