Answer:
0
Step-by-step explanation:
In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite, sign change, and negation.
Hence, -96 + 96 = 0
Tan (x + pi/2) = -cot x
<span>tan (pi/6 + pi/2) = -cot (pi/6) </span>
<span>tan (2pi/3) = -cot (pi/6) </span>
<span>-sqrt (3) = -[sqrt 3] <<< so it is true for x = pi/6</span>
Answer:
4(5+4)
Step-by-step explanation:
4(5+4) equals 36, and 20 + 16 equals 36 as well, so therefore 20 + 16 is equivalent to 4(5+4)
