Find the sum and Express it in simplest form. (-8n^3 + 4n - 8) + (7n^3 - 2n + 6)
Please Help !

Step-by-step explanation:

We have to add the like terms. Like terms are with variables of same power.

-8n³ and 7n³  are like terms , now add the coefficient of n³ , -8 + 7 = -1

-8n³ + 7n³ = -1n³

(-8n³ + 4n - 8) + (7n³ - 2n + 6 )

Combine like terms

= -8n³ + 7n³    + 4n - 2n  - 8 + 6

= -1n³ + 2n - 2

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

where are the images of the functions i can only see the question you typed.
