A rectangle has a height of 5 and a width of 4x^2-2x-6 . Express the area of the entire rectangle.

20x² - 10x - 30

Step-by-step explanation:

Height = 5

Width = 4x² - 2x - 6

Area of rectangle = length × breadth

Area of triangle = height × width

Area = 5 × (4x² - 2x - 6)

Area = 20x² - 10x - 30

Area of the rectangle is 20x² - 10x - 30

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
