7 + 14 + 21 + ... + 105 =
= 7(1 + 2 + 3 + ... + 15)
= 7(15)(16)/2
= 840
The answer is 0.583, and the 3 has a bar notation
Hope this helped
btw i also do k12
Answer:
77 degrees c:
Step-by-step explanation:
To get the answer to this equation you first cancel out the 6! ;)
(x^2-1)(6x-1) / (x+1)
Then rewrite x^2-1 in the form a^2 + b^2, where a=x and b=1
(x^2-1^2)(6x-1) / (x+1)
Then use the difference of squares!
(x+1)(x-1)(6x-1) / (x+1)
LASTLY cancel "x+1" !
so ur answer is (x-1) (6x-1)
That makes the correct answer to this problem answer choice (D) (x-1) (6x-1)
YW!!! ;)
Factor both the top and bottom.
(2(x-6)(x-2))/((x+6)(x-4))
To find zeros, the numerator must be 0. The denominator cannot be 0 because anything divided by 0 is infinity.
(x-6)=0
x=6
(x-2)=0
x=2
Final answer: x=2, x=6
