3x = -12
x = -4

9(-4) - 9y = -18
-36 - 9y = -18
-9y = 18
y = -2

52/4=13 (since it's a square you divide it by 4 because the sides are equal, so each side is 13 meters)

13^2=169 (to find the area you square the length of each side)

Let's move like a crab, backwards some.

$\bf ~~~~~~ \textit{Compound Interest Earned Amount}

A=1000\left(1+\frac{0.03}{1}\right)^{1\cdot 2}\implies A=1000(1.03)^2$

is that enough to pay the $1100?

now, let's write 1000(1+r)² in standard form

1000( 1² + 2r + r²)

1000(1 + 2r + r²)

1000 + 2000r + 1000r²

1000r² + 2000r + 1000 <---- standard form.
