Formula- Area = L • W
So...
Length = 18 + 3
Width = 18 + 3
Since you’re adding 18 + 3 for Length AND Width, you’re going to get a sum of 21 for each.
Length = 21
Width = 21
Now you’re gonna want to multiply 21 by itself.
21 • 21 = 21 + 420 = ?
Which leaves you with the final sum of...
Area = 441 yds.
Answer:
10 years until the value of the car is 11000 dollars
Step-by-step explanation:
The value of the car after t years is modeled by the following equation:
In which V(0) is the initial value and r is the yearly depreciation ratio, as a decimal.
A new car is purchased for 21100 dollars.
This means that
The value of the car depreciates at 6% per year.
This means that . So
To the nearest year, how long will it be until the value of the car is 11000 dollars?
This is t when
To the nearest year
10 years until the value of the car is 11000 dollars
The exponential model would take the form:
A, the initial value is 2, we will use 3 days and 8 tops to find k, or the rate.
Now, plugging in 6 days:
The linear would take the form:
y = mx+b
First the slope would be: (8-2)/(3-1) = 3
And to find b we could plug in the point (8,3):
8 = 3(3)+b
b = 8-9
b = -1
y = 3x-1
At x=6
y = 3(6)-1
y = 17
Thus, the exponential is almost double the result of the linear! Hope that helps.

Answer:
-7 is what i got
Step-by-step explanation:
combine like terms.. 6n -2n= 4n
7-14= -7
4n-7= 5n+1
+1 becomes -1
4n- -6=5n
-4n on both sides
-6= 1n
1-1 on both sides to cancel out
n= -7
