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

I believe that the answer is 21x+14 and 7(3x+2).

Step-by-step explanation:

I hope this helps, have a blessed day.

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

Step-by-step 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).

because they could drop even lower..

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
