Question

Combine like terms . what is 43z + 15z + 7z + 5z + 46z + 14z? ​

Answer 1

Basically just add them all together like normal addition except there is a z attached to each number:

43z + 15z + 7z + 5z + 46z + 14z

58z+ 7z + 5z + 46z + 14z

65z + 5z + 46z + 14z

70z + 46z + 14z

116z + 14z

130z

Hope this helped!

Answer 2

130z

Explanation:

43z + 15z + 7z + 5z + 46z + 14z

Since the all have z with a coefficient, they are all like terms

Factor out a z

(43 + 15 + 7 + 5 + 46 + 14 ​ )z

Then add all the coefficients together

(130)z

The total is 130z
