Question

Simplify:

6m + 7n + 5m – 3n

Answer 1

you can only add like terms

6m + 7n + 5m - 3n

6m + 5m = 11m
7n - 3n = 4n

giving us : 11m + 4n

Answer 2

Which are the like terms in 2y3 – 4y2 + y + y3?

Answer 3

2y^3-4y^2+y+y^3?

Answer 4

like terms :
2x and x, or 3x^2 and 4x^2, or x^3 and 2x^3

so your problem....2y^3 - 4y^2 + y + y^3
the only like terms in this problem is the y^3's

answer is : 3y^3 - 4y^2 + y (because 2y^3 + y^3 = 3y^3...there are no other like terms)

Answer 5

Answer 6

7^-3
