Step-by-step explanation:
1/2 x 4 x 2
It is different because partial products is you part the number to get the answer.They are the same because both strategies give you the same answer. Hope it helps
3x-50=7x+80
I think this is correct! Hope I helped!
(−8* y^2−9*y)+(8*y^3+9*y^2−2*y)
first, remove extraneous parentheses (or distribute if negative)
=−8* y^2−9*y+8*y^3+9*y^2−2*y
then group terms in decreasing degree of y (variable)
=+8*y^3 −8* y^2+9*y^2 −9*y−2*y
simply expression by adding/subtracting similar terms
=+8*y^3 +y^2 −11*y
to give the final answer.
