Answer:
Area = 2x^2 -5x-12
Step-by-step explanation:
Area = length * width
Area = (2x+3) * (x-4)
We will use the FOIL technique to multiply the terms.
First: 2x*x = 2x^2
Outer: 2x* -4 = -8x
Inner: 3*x = 3x
Last = 3* -4 = -12
Add the 4 terms together: 2x^2 -8x+3x -12 = 2x^2 -5x-12
Area = 2x^2 -5x-12
Answer: 2x^2 - 5x - 12
Step-by-step explanation: The correct answer is 2x^2 - 5x - 12. To find the area of a rectangle you multiply the length by the width. So you multiply (2x + 3)(x - 4) using the FOIL method.
