Answer: D) x+4+x+4
The two x terms combine to x+x = 2x
The other pair of like terms, the constants, add to 4+4 = 8
Overall we get 2x+8
2x+8 is also equivalent to 2(x+4) when you factor out the GCF 2.

Answer:
<h2>45, 46, 47</h2>
Step-by-step explanation:
n, n + 1, n + 2 - three consecutive integers
The equation:
138 - n = (n + 1) + (n + 2)
138 - n = n + 1 + n + 2 <em>combile like terms</em>
138 - n = 2n + 3 <em>subtract 138 from both sides</em>
-n = 2n - 135 <em>subtract 2n from both sides</em>
-3n = -135 <em>divide both sides by (-3)</em>
n = 45
n + 1 = 46
n + 2 = 47
Answer:
