1. x(x+3) = x²+3x
Step by Step:
Apply the Distributive law: (a=x, b=x, c=3)
= xx + x × 3
= xx + 3x
= xx = x²
= x²+3x
-----------------------------------------------------------
2. 3x(4x-7) = 12x²-21x
Step by Step:
Apply the Distributive law: a(b-c) = ab - ac
(a=3x, b=4x, c=7)
= 3x × 4x - 3x × 7
= 3 × 4xx - 3 × 7x
= 12x² - 21x
-----------------------------------------------------------
3. -5x(6x-2) = -30x²+10x
Step by Step:
Apply the Distributive law: a(b-c) = ab - ac
(a = -5x, b = 6x, c = 2)
= -5x × 6x - (-5x) × 2
Apply minus - plus rule: -(-a) = a
= -5x × 6xx + 5 × 2x
= -30x² + 10x
-----------------------------------------------------------
1. x(x+3) = x²+3x
2. 3x(4x-7) = 12x²-21x
3. -5x(6x-2) = -30x² + 10x
Answer:
b. behaviorism
Explanation:
According to my research on different studies conducted by various psychologists, I can say that based on the information provided within the question the term being mentioned in the question is called Behaviorism. This is a learning theory that focuses on the approach to understanding the behavior of humans and other animals. Behaviorists believe that the way we react to environmental stimuli shape our actions. Which is why they would be concerned with the influence of the general principles of learning on an organism's or a person's actions.

Answer:
The sleeper effect.
Explanation:
As the exercise presents, Jamie heard about a divorce that was published in the RAG MAG, which she does not believe is very reliable. However, over time, she forgot where she heard about the divorce. The fact that she later came to believe the story was true is known as the sleeper effect. The sleeper effect is, as suggested, a psychological phenomenon that relates to persuasion. It is a delayed increase of the effect of a message that is accompanied by a discounting cue. So, in this case, Jamie heard statement X from place A. After some time, she forgot where she had heard it, but the information (statement X) remained in her mind.
