Final answer:

The expression representing the area of a rectangle with width 2x and length x² - x + 3 is 2x³ - 2x² + 6x.

Step-by-step explanation:

The area of a rectangle is found by multiplying the width by the length. In this case, the width of the rectangle is represented by 2x, and the length is represented by x2 - x + 3. To get the expression representing the area, we multiply these two expressions:

Area = width × length

Area = (2x) × (x² - x + 3)

Applying the distributive property:

Area = 2x ×x²+ 2x × (-x) + 2x × 3

Area = 2x³ - 2x² + 6x.

So, the expression that represents the area of the rectangle is2x³ - 2x² + 6x.

Answer:

x2 ->

Step-by-step explanation:

Width area = long edge × short edge

= (2+3x).(x-4)

= 2x-8+3x²-12x

= 3x²-8-10x

= 3x²-10x-8

= x2 ->
