Answer:
2a+5b
Step-by-step explanation:
7a-5a =2a
-2b+7b = 5b
By definition,
Any number that is subtracted 0 units, is equal to the original number.
We have then:
Then, on the other hand we have:
In the division of numbers, the result of dividing 0 by any real number other than 0 is equal to 0.
We have then:
Tan9−tan27−tan63−tan81
tan9+tan81−tan27−tan63
sin9/cos9+sin81/cos81−sin27/cos27−sin63/cos63
sin90/cos81cos9−sin90/cos63cos27
1/sin9cos9−1/sin27cos27
2/sin18−2/sin54
(2)sin54−sin18/sin18sin54
4cos36sin18/sin18cos36=4
