Answer:
D. difference of squares
Step-by-step explanation:
Both of the terms x^2 and 9 are squares, so their difference is the difference of squares. The factorization of that is a "special form" that can be usefully memorized.
a^2 -b^2 = (a -b)(a +b)
x^2 -9 = (x -3)(x +3)

Answer:
4.25%
Step-by-step explanation:
<u>Step 1: Calculate the commission paid</u>
<em>Commission = Gross earning - base salary</em>
<em>Commission = 441.3 - 375</em>
Commission = 66.3
<u>Step 2: Calculate the commission sales</u>
<em>Commission sales = Total sales - quota sales</em>
<em>Commission sales = 6560 - 5000</em>
Commission sales = 1560
<u>Step 3: Calculate the rate of commission</u>
<em>x% of 1560 = 66.3</em>
<em>x% * 1560 = 66.3</em>
<em>x% = 0.0425</em>
x = 4.25%
Therefore, the rate of commission was 4.25%.

Answer:
q = 270 degrees + 360n where n is an integer
Step-by-step explanation:
2 sin q + 3 = sin q + 2
Subtract sin q from each side
2 sin q - sin q + 3 = sin q + 2
sin q + 3 = 2
Subtract 3 from each side
sin q +3-3 = 2-3
sin q = -1
Take the inverse sin of each side
sin ^-1 (sin q) = sin^-1 (-1)
q = 270 degrees + 360n where n is an integer
