Answer:
C
Step-by-step explanation:
Add like terms to get
4.5a + 4b + 3.5c
1.) 17? (8^2=64) - (9^2=81) 81-64= 17
2.) 625? (40/8=5 5^2=25 25x5= 625
3.) 0? (24/4=6) 6^2=36/6=6-6=0
I think these are correct. Sorry if they are not. The only way it would be incorrect is if I did the steps out of order. I don’t think I did but it’s possible. Good luck! Sorry, Hope this helps
Answer:
The average price of a gallon of orange increased by $0.03 each month.
Step-by-step explanation:
It is 11 months between October 2013 and September 2014 so the price after 11 months =
f(11) = 6.12 + 0.03(11)
= 6.12 + 0.33
= $6.45.
This is an increase of 0.33 / 11 = 0.03 / month.
Answer:
125
Step-by-step explanation:
The power of a number 
says how many times to use the number in a multiplication. It is written as a small number to the right and above the base number ( 
).
To find the value of 
you have to multiply n numbers a:
![a^n=a\cdot a\cdot \dots\cdot a\ [\text{Multiply n numbers } a]](https://tex.z-dn.net/?f=a%5En%3Da%5Ccdot%20a%5Ccdot%20%5Cdots%5Ccdot%20a%5C%20%5B%5Ctext%7BMultiply%20n%20numbers%20%7D%20a%5D)
You have to find 
Use the definition of powers:
![5^3=5\cdot 5\cdot 5\ [\text{Multiply three numbers 5}]\\ \\5^3=25\cdot 5\\ \\5^3=125](https://tex.z-dn.net/?f=5%5E3%3D5%5Ccdot%205%5Ccdot%205%5C%20%5B%5Ctext%7BMultiply%20three%20numbers%205%7D%5D%5C%5C%20%5C%5C5%5E3%3D25%5Ccdot%205%5C%5C%20%5C%5C5%5E3%3D125)
1) a = 3189 b = 5
2) a = 53 b = -5
