Question

Which of the following represents the area of a rectangle whose length is 3x + 5 and whose width is. x – 2?.

A.) 3x^2 + x – 10
B.) 3x^2 – 10
C.) 3x^2 – 11x – 10
D.) 3x^2 – x – 10

Answer 1

A = L * W
A = (3x + 5)(x - 2)
A = 3x^2 - 6x + 5x - 10
A = 3x^2 - x - 10

Answer 2

Area of a rectangle is expressed as the product of length and width. 

Area = l x w
Area = (3x+5)(x-2)
Area = 3x² - 6x + 5x - 10
Area =  3x² - x - 10

Therefore, the correct answer is option D.
