Question

Please help lots of points

Answer 1

The area is given by

A = l*w

A = (4x-1) ( 3x+6)

first 4x*3x =12x^2

outer 6*4x = 24x

inner -1*3x = -3x

last -1 *6 = -6

Add together

12x^2 +24x-3x-6

12x^2 +21x-6

Answer 2

see below

Explanation:

The area is given by

A = l*w

A = (4x-1) ( 3x+6)

FOIL

first 4x*3x =12x^2

outer 6*4x = 24x

inner -1*3x = -3x

last -1 *6 = -6

Add together

12x^2 +24x-3x-6

12x^2 +21x-6
