Answer:
-3x^3+7y^2+9y
Step-by-step explanation:
y - y² + 4y + 7y² – 3 x3 + y² + 4y
Combine Like Terms:
=y+−y2+4y+7y2+−3x3+y2+4y
=(−3x3)+(−y2+7y2+y2)+(y+4y+4y)
=−3x3+7y2+9y
To represent the product of 6 and 7, we could use (6)(7). To represent 5 less than this, we will need to subtract 5 from the expression. Using this, the expression would look like:
![\boxed{(6)(7) - 5}](https://tex.z-dn.net/?f=%5Cboxed%7B%286%29%287%29%20-%205%7D)
To simplify it, we should follow the order of operations. First, we will need to do the multiplication, and then we can do the subtraction. (6)(7) is equal to 42. Subtracting 5 from 42, we get 37. Thus, the simplification leads to 37.
