Answer:

320 meters

Step-by-step explanation:

x² + 200x = 166400

It's a square, area should be side²

x² + 2(x)(100) = 166400

x² + 2(x)(100) + 100² = 166400 + 100²

(x + 100)² = 176400

x + 100 = 420

Since these are sides, we just consider the positive square root

x + 100 = 420

x = 320m

Answer:

Javier's parents set aside $1500 when he was born

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

$E = P*I*t$

In which E is the interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

In this question, we have that:

$E = 1012.50, t = 15, I = 0.045$

We have to find P. So

$E = P*I*t$

$1012.50 = P*15*0.045$

$P = \frac{1012.50}{15*0.045}$

$P = 1500$
