Taking log on both sides
Plugging the value of log e as 1
..................... Answer
Hope it will help :)
The area of a square is A=s² (s being the side). Since you know this, you can write an equation.
A=(6a - 2b)²
Expanding this would give you,
A=(6a - 2b)(6a - 2b)
Then to solve this you would want to FOIL (Multiply first terms, multiply outer terms, multiply inner terms, multiply last terms)
36a² - 12ab - 12ab + 4b²
Then combine like terms,
36a² -24ab + 4b²
So the answer would be D

Answer:
20 pounds of Gummyballs and 5 pounds of caramel was ordered
Step-by-step explanation:
Let :
Gummyball = a
Caramel = b
a + b = 25 - - - (1)
5a + 8b = 140 - - - (2)
From (1)
a = 25 - b
Put into (2)
5(25 - b) + 8b = 140
125 - 5b + 8b = 140
125 + 3b = 140
3b = 15
b = 5
From a = 25 - b
a = 25 - 5
a = 20
Hence,
20 pounds of Gummyballs and 5 pounds of caramel was ordered
Step-by-step explanation:
Step one:
given data
we are told that she wants her balance to be at least $100
y=100-------1
the expression relating her current balance and spending rate is
let y be the total and m be the number of months
y=330-11m----------2
Required
the number of months m
equating 1 and 2 we have
100=330-11m
11m=330-100
11m=230
m=230/11
m=20.9
m=21 approx
This means that she will keep her account open for 1 year 9 months
