Combine like terms. 3a + 4a + a - 2a O a. 5a O b.6a2 Olc.6a O d. - 24a O e. Already simplified

Answer 1

c. 6a

Explanation:

Like terms have the same variable part. The variable part of 3a, 4a, a, and -2a is a. Since the 4 terms have the same variable part, they can be combined. To combine, just add or subtract the numbers. Then write the variable after the number.

Add: 3 + 4 + 1 - 2 = 6

3a + 4a + a - 2a =

= 6a
