8. Part A The area A of the rectangle shown is described with the inequality100 ≤A≤1,000. Select the compound inequality for the area written in termsof x. Length is 4x width is 5. A. 100 ≤ 10 + 8x ≤ 1,000B. 100 ≤ 18x ≤ 1,000C. 100 ≤ 9x ≤ 1,000D. 100 ≤ 20x ≤ 1,000

Respuesta :

Answer:

(D)100 ≤ 20x ≤ 1,000

Explanation:

Given that:

Length of the rectangle = 4x

Width of the rectangle = 5

Area of the rectangle = Length x Width

=4x x 5

=20x

Therefore, the compound inequality for the area written in terms of x is:

100 ≤ 20x ≤ 1,000

The correct choice is D.
