49x^2 + -9 = 0
Reorder the terms:
-9 + 49x^2 = 0
Solving
-9 + 49x^2 = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '9' to each side of the equation.
-9 + 9 + 49x^2 = 0 + 9
Combine like terms: -9 + 9 = 0
0 + 49x^2 = 0 + 9
49x^2 = 0 + 9
Combine like terms: 0 + 9 = 9
49x^2 = 9
Divide each side by '49'.
x^2 = 0.1836734694
Simplifying
x^2 = 0.1836734694
Take the square root of each side:
x = {-0.428571429, 0.428571429}

Answer:
Compound interest is the best.
Step-by-step explanation:
Simple interest is that which is not added to the initial capital once the term of the investment or credit has expired.
Compound interest is that which is added to the initial capital at the end of the investment or credit.
Simple interest:
I= C x i x t
15,000 * 0.05 * 5 = $ 750
Compound interest:
Cf= Ci (1+i)ᵗ
Cf = 15,000 * (1.039)^5 = $ 18,162.22
So, if Cf - Ci = I -> 3,162.22 is the compound interest.
this is how i calculated for x!

"At most 12" means "the highest we can go is 12". Think of it as the ceiling. So x can equal 12 or it can be smaller. This means
