-5 (x - 3)= 30 ....x=3 is not a solution
-5(x - 3)= 30 -5x +15
(Two minus’ would cancel each other out)
If x =3 then the equation would be -15 +15 which equals 0 x would have to be -3 for the equation to be true
Answer:
Example a) the resulting vector is 54 degrees with a force of 48N (4.8cm)
Example b) the resulting vector is 168 degrees with a force of 38N
Example c) the resulting vector is 129 degrees with a force of 57N
Step-by-step explanation:
i had the same assignment so i used the vector calculator online
The answer would be 2√5/5
As a rule, you cannot have any radical as a denominator. That's why you gotta multiply √5 with √5 which would be √25. The square root of this is 5, and now you have disposed of the radical! Hurray. However, keep in mind, that when you multiply √5, you also multiply it to the numerator. So, yeah, after this, you get the answer.
Hopefully, my explanation makes sense. :)
