(w5 + 2w3 – 3) + (2w5 – 3w3 – 4)?

Question

Add:

(w5 + 2w3 – 3) + (2w5 – 3w3 – 4)

Thanks!

Answer 1

(w5 + 2w3 - 3) + (2w5 - 3w3 - 4)
= 5w + 6w - 3 + 10w - 9w - 4
= 11w - 3 + 1w - 4
= 12w - 7
12w = 7
w = 7/12

Answer 2

3 w^5 - w ³ - 7

Answer 3

If the number after the variable w is an exponent, then:

w^5 + 2w^3 - 3 +2w^5 - 3w^3 - 4, then combine all similar terms. (when we say similar terms, it means that variable and exponent must be the same)

3w^5 - w^3 - 7

Answer 4

Combine like terms:
w^5 + 2w^5 = 3w^5
2w^3 + (-3w^3) = -w^3
-3 + (-4) = -7
writing as one expression: 3w^5 - w^3 - 7

Answer 5

The gist of the communicate accessible (sorry, there are too many pages to grant each and all the hyperlinks) is that wands help to concentration the magic resident interior the witch or wizard, yet wandless magic remains achievable, fairly for extremely gifted people like Snape and Dumbledore. some examples ...
