Looks like all you have to do is to translate this expression into symbols:
2.1*10^9
Square area=side^2
15=area=side^2
sqrt both sides
√15=side
aprox
3.87298=side

Answer:
2%
Step-by-step explanation:
Chloe's simple interest for 1 year is $4. You can get this by subtracting the amount she invested from the total amount she got after one year.
Now that we know the simple interest, we can now get the simple interest rate or<em> simple percent interest per year </em>by dividing $4 by $200.
Let's change 0.02 into a percentage.
This means that every year, her investment will earn a <em>2% simple interest.</em>
look at the whole numbers and not the tenths and hundreds and stuff.
