Answer:
area = Iw
Explanation:
area = lw
where
l = length
w = width
Therefore,
The area of the shaded region = area of the big rectangle - area of the small rectangle
Therefore,
area of the big rectangle = (x+10)(2x+5) = 2x² + 5x + 20x + 50 = 2x² + 25x + 50
area of the small rectangle = (x+1)(x+1) = x² + x + x + 1 = x² + 2x + 1
area of the shaded region = 2x² + 25x + 50 - ( x² + 2x + 1)
area of the shaded region = 2x² + 25x + 50 - x² - 2x - 1
area of the shaded region = x² - 23x - 49
A. The pigs use lies and deceit to control the other animals.
Explanation:
Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction. The reactivity of metal is determined by a series known as reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the series
The answer option which is considered to be true of analogies in supporting problem solving is: Relevant analogies usually help people solve problems, and people do spontaneously think of relevant analogies.
An analogy can be defined as a process through which a situation is compared with another for the purpose of clarity or explanation. Thus, an analogy can be used to explain and illustrate the relationship that exist between two or more things.
In the problem-solving process, an analogy uses relevant or similar situations to proffer a solution to a problem since there exist a relationship between the two circumstances.
In conclusion, relevant analogies usually help people in proffering solution to problems.
