Combine like terms to simplify an expression. For example, all terms with the variable x can be combined into one term. All constants can also be combined.
1) -4x - 10x = -14x
2) -r - 10r = -11r
3) -2x + 11 +6x = 4x + 11
4) 11r - 12r = -r
5) -v + 12v = 11v
6) -8x - 11x = -19x
7) 4p + 2p = 6p
8) 5n + 11n = 16n
9) n + 4 - 9 - 5n = -4n - 5
10) 12r + 5 + 3r - 5 = 15r (the 5 and -5 cancel each other out)
11) -5 + 9n + 6 = 9n + 1
Answer:

Answer:
10ˣ² +19ˣ + 6
Step-by-step explanation:
5ˣ(2x + 3) + 2 (2x + 3 )
10x² + 15x + 2(2x + 3 )
10x² + 15x + 4x + 6
= 10x² + 19x + 6
Answer:
The answer is letter 'J'
Step-by-step explanation:
4(3+5) - 3 x 9^2
4(8) - 3 x 9^2 ← 9 x 9 = 81
16 - 3 x 9^2
16 - 3 x 81
13 x 81
