Answer:

D. 8x²-2x-3

Step-by-step explanation:

Area of Rectangle=Length×Width

(4x-3)(2x+1)

Do this using the FOIL Method (First, Outer, Inner, Last)

(4x)(2x)+(4x)(1)-(3)(2x)-(3)(1)

8x²+4x-6x-3

Answer:

A. 8x^2 - 2x - 3

Step-by-step explanation:

Length (l) = 4x - 3

Width (w) = 2x + 1

A = lw

A = (4x - 3)(2x + 1)

A = 8x^2 + 4x - 6x - 3

A = 8x^2 - 2x - 3
