Amount of money Ann earned this week = Amount of money earned in 1hour × Number of Hours she worked
Amount of money Ann earned this week = (4x + 3) × (2x - 1)
= (4x + 3) (2x - 1)
{Draw lines like rainbows to let yourself know which numbers to multiply by}
= (4x × 2x) + [4x × (-1)] + (3 × 2x) + [3 × (-1)]
{Always remember to put in the negative signs if the number if negative}
= 6x^2 + (-4x) + 6x + (-3)
= 6x^2 - 4x + 6x - 3
{Simplify}
= 6x^2 + 2x - 3

The study that Dr. Keyes wants to do is a study that uses two variables (pets and happiness). Dr. Keyes wishes to prove the cause and effect relationship between these two variables that prove that the greater the amount of pets (causes) people have, the greater the happiness of these people (effect). For this reason, we can say that Dr. Keyes is not doing a correlational study.
This is because, although the correlational study wishes to observe the relationship between two variables, this study cannot be applied to cause and effect relationships.

The landlords were left with no choice but to <em>substitute labor service for rental payment</em>.
The plague resulted to the blaming of different religions. It also blamed the<em> lepers, foreigners and beggars</em> as being the cause of it.<em> People with skin diseases</em> were then killed in Europe.
