While on a trek, ben gets bitten by a snake. he notices the color and size of the snake and realizes that the snake is not poisonous. in this scenario, ben has most likely used his to recall that the snake is not poisonous.

While on a trek, Ben gets bitten by a snake. He notices the color and size of the snake and realizes that the snake is not poisonous. In this scenario, Ben has most likely used his semantic memory to recall that the snake is not poisonous.

Explanation:

In psychology, a semantic memory can be described as a part of long- term memory which is generated through ideas which were not personally encountered by a person. In other terms, it can be described as memory which arises from general knowledge of the world.

In the scenario mentioned in the question, Ben used his semantic memory to recall that the snake is not poisonous. He might have not encountered this situation before but got his memory from other things where he might have read or seen a documentary about the thus type of snake.  

x = 7

step-by-step explanation:

equating the expression for area to the given area

2x² - 7x - 4 = 45 ( subtract 45 from both sides )

2x² - 7x - 49 = 0 ← in standard form

to factor consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 49 = - 98 and sum = - 7

the factors are - 14 and + 7

use these factors to split the middle term

2x² - 14x + 7x - 49 = 0 ( factor the first/second and third/fourth terms )

2x(x - 7) + 7(x - 7) = 0 ← factor out (x - 7)

(x - 7)(2x + 7) = 0

equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

2x + 7 = 0 ⇒ 2x = - 7 ⇒ x = -

thus the positive value for x is x = 7

this question your asking is true hope this and you get a 100 percent : )
