x + x + 5 and x2 + 5
9x2 + 9x + 5 and 18x2 + 5
PLS ANSWER

Answer 1

A. 21x + 14 and 7(3x + 2).

Explanation:

23x - 14 + 2x = 21x + 14

25x - 14 ≠ 21x + 14

x + x + 5 = x² + 5

2x + 5 ≠ x² + 5

9x² + 9x + 5 ≠ 18x² + 5

21x + 14 = 7(3x + 2)

21x + 14 = 21x + 14.

Your answer is A, 21x + 14 and 7(3x + 2).
