Question

Which expressions are equivalent to 4(4x + 2y + x − y)? (1 point)

Group of answer choices

4(3x + y) and 12x + 4y

4(3x + 3y) and 12x + 12y

4(5x + y) and 20x + 4y

4(5x + 3y) and 20x + 12y

Answer 1

=4(4x+2y+x-y)
=4*4x+4*2y+4*x-4*y
=16x+8y+4x-4y
=16x+4x+8y-4y
=20x+4y

donc la bonne reponse est la 3
4(5x+y)*
=4*5x+4*y
=20x+4y
