Answer:
Step-by-step explanation:
Let us consider the given terms one by one:
First term, 
= 6
Second term, 
Difference between First and Second term = 2 - 6 = -4
Third term, 
= -2
Difference between Second and Third term = -2 - 2 = -4
Fourth term, 
= -6
Difference between Second and Third term = -6 -(-2) = -4
Therefore, the common difference is:
= -4
Let the use the formula for 
term of an arithmetic sequence:
Putting the values of and :
Therefore, the term is:
Answer:
45 - 25 = 20 / 10 = 2 meaning he used the boat for 2 hours.
Step-by-step explanation:
Its the same this as before you start by writing it out how the way PEMDAS works. PEMDAS is ( Parenthesis, Exponents, Multiplication, Division, Adding, and Subtraction). Also i accidentally messed up my other answer so give me a sec.
Answer:
√85
Step-by-step explanation:
A (-3 , 4) B (4 , -2)
AB² = (4 - -3)² + (-2 -4)² = 49 + 36 = 85
AB = √85

Answer: Choice A. x^2+9</h3>
This is a sum of squares, which cannot be factored over the real numbers. You'll need to involve complex numbers to be able to factor, though its likely your teacher hasn't covered that topic yet (though I could be mistaken and your teacher has mentioned it).
Choice B can be factored through the difference of squares rule. Therefore, choice B is not prime.
Choice C and D can be factored by pulling out the GCF and then use the difference of squares rule afterward. So we can rule out C and D as well.
