mkay... whats the question?

OpenStudy (iiariana):

Which of the following is equivalent to the expression below? (5x 6y 3z) (3x 8y z) A. 8x 14y 4z B. 8x 2y 2z C. 8x 14y 2z D. 8x 2y 3z

OpenStudy (jack1):

(5x 6y 3z) (3x 8y z)... is that supposed to be \((5x + 6y + 3z) + (3x +8y+ z)\)??

OpenStudy (iiariana):

yes

OpenStudy (jack1):

ok... then there's no need for the brackets so lose the brackets and add like terms together and you will have your answer (5x+6y+3z)+(3x+8y+z) 5x+6y+3z+3x+8y+z 5x+3x+8y+6y+3z+z =??

OpenStudy (iiariana):

Ok

OpenStudy (jack1):

OpenStudy (iiariana):

OpenStudy (jack1):
