Anation that has new or emerging industry, minimal infrastructure, and widespread poverty is generally referred to as a(n) a. industrialized nation b. developing nation c. economically struggling nation d. developed nation

The correct answer is B. Developing nation

Explanation:

Countries can be classified as developed nations, developed nations or underdeveloped nations depending on their economy and other factors such as education, health, poverty, etc. In the case of developing nations, these are nations that are not as developed as industrialized or developed nations but have already begin a process for expanding industry and improving conditions. Because of this, developing nations are characterized by an emerging economy with developing infrastructure but a low Human Development Index which implies a high poverty rate, low quality in education and low quality in health. According to this, a nation that has a new industry, minimal infrastructure and poverty is a developing nation.

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
