The third term of the binomial expansion of (2x + 5)⁵ is <span>
2000x³.</span>The first term of the expansion is when r = 0 ; thus the second is when r = 1 and the third when r = 2.
The terms of the expansion are:
<span>32x</span>⁵ <span>+ <span>400x</span></span>⁴ <span>+ <span>
2000x</span></span>

Answer:
D. 18
Step-by-step explanation:
The polygon given is a 5-sided polygon (pentagon). Sum of all interior angles of a 5-sided polygon = (n - 2) * 180°
= (5 - 2) * 180 = 540°
Therefore:
95° + (7x - 4)° + (3x + 23)° + (9x - 6)° + 90° = 540°
Solve for x
95 + 7x - 4 + 3x + 23 + 9x - 6 + 90 = 540
Add like terms
198 + 19x = 540
19x = 540 - 198
19x = 342
x = 342/19
x = 18
