To find the rate add 1 to the annual rate divided by 365 days raised to the number of days left in the year minus 1.

r= (1 + 0.2319/365)^305 - 1

r = 0.2138

Now multiply by 100 for the percent:

0.2138 x 100 = 21.38%

Answer:

A. $x(x+12) -7(x+12)$

Step-by-step explanation:

Factoring is the process of taking common terms out of an expression such that one can represent the expression as the result of smaller values. When given the following expression:

$x^2 +5x - 84$

First, represent the linear term as the sum of two terms such that each term shares a common factor with the other terms in the expression.

$x^2 +12x - 7x - 84$

Now take out the common factors,

$x(x+12) -7(x+12)$

Thus, the correct option is choice (A).
