Answer:

\frac{1}{4}

Step-by-step explanation:

x² + x

To complete the square

add ( half the coefficient of the x- term )² to x² + x

x² + 2(\frac{1}{2} )x + (\frac{1}{2} )² = x² + x + \frac{1}{4}

= (x + \frac{1}{2} )² ← perfect square

A savings account earns 5% simple interest per year. The principal is $1200. What is the balance after 4 years?
stiv31 [10]
The formula of the Simple Interest is:
I=PRT
P for Principle Amount     ($1200)
R for Rate                        (5%=\frac{5}{100} = 0.05)
T for Time in years          (4 years)
I = 1200 × 0.05 × 4
  = $240

Add the interest to the principle amount to check the balance
$1200 + $240 = $1440
