The area of a square is
s • s
We can also write this as
s^2
So, for any side length “s”, we can make a function, A(s), such that
A(s) = s^2
Now that we have a quadratic equation for the area of a square, let’s go ahead and solve for the side lengths of a square with a given area. In this case, 225 in^2
225 = s^2
Therefore,
s = sqrt(225)
s = 15
So, the dimensions are 15 x 15 in
The equation for inflation is
A = P*(1+r)^t
which is an exponential growth equation (if r > 0). If r < 0, then we have deflation.
where...
A = final price after t years
P = initial starting price
r = rate of inflation in decimal form
t = number of years
In this case,
A = unknown (we're solving for this)
P = 280 is the starting price
r = 0.05 is the decimal form of 5%
t = 2 years
We will plug these three pieces of info into the formula to get...
A = P*(1+r)^t
A = 280*(1+0.05)^2
A = 280*(1.05)^2
A = 280*(1.1025)
A = 308.70

Step-by-step explanation:
Hello!
The expression is written in the form of 
Let's factor by grouping:
The sum of the factors of -50 should add up to -23.
-25 and 2 work for this.
Expand and factor:
The factored expression is
so the line is dog so we know the full line is 60 units long. The 2 parts (do and og) add up to the full length so we can make the equation:
(4x-3)+(2x+21)=60
6x+18=60
6x=42
x=7
if you need to fine do or og, just plug in x to its equation
