Answer:
this is school work
Step-by-step explanation: sorry but you gotta figure this out yourself.
but, the thing is that you should figure out the stuff inside the (these -->) then figure out the rest step by step like this, x= what then try to understand y= what, then use them to answer the problem.
and if its like this 1(4x + 5y) that mean that 9xy times 1 is your answer, this is an example.
Answer:
x ≤ -10
Step-by-step explanation:
distribute -2 into your denominator (5)
126 1/4 - 78 2/3 =
505/4 - 236/3 =
1515/12 - 944/12 =
571/12 =
47 7/12 <==
Answer:
√13 ≈ 3.6056
Step-by-step explanation:
The Law of Cosines can be used to figure this. If the third side is "c", then it tells you ...
c² = a² + b² - 2ab·cos(C)
c² = 3² + 4² -2(3)(4)(cos(60°)) = 9 + 16 - 24(1/2) = 13
c = √13 ≈ 3.6056
The length of the third side is √13, about 3.6056.
