The one which says it is "6x".
If that is not one of the statements, then you'll have to re-ask the question INCLUDING the statements so that your question NO LONGER CONTAINS INSUFFICIENT INFORMATION for it to be answered.

How do you factor 2x3-42x2-200x?
2x(x + 4)(x - 25)
42x2 is what?
84
42x2 - 6x 35x - 5?
(7x - 1)(6x + 5)
16x2 - 49 equals?
16x2 - 49 = 42x2 - 72 = (4x)2 - 72 = (4x - 7)(4x + 7)
What is 42x2 - 69x plus 20 equals 7x2 - 8?
X=16 (i failed Algebra so it's probably wrong :D )
Is 84 divisible by 2?
84 divided by 2 = 42 to check Ur answer you can multiply 42x2.
What is 4 squared multiplied by 2 to the fourth power?
To find the answer, one does 4x4 to get your 4 squared. Then times that by 2. Then times that 4 times. It should look like this: (42x2)4 (16x2)4 (32)4 32x32x32x32 1,048,576
Kari checked her pluse and counted 21 beats in 15 seconds so how many BEATSwill be there in 30 seconds?
Seriously? 30/15=2 21x2=42... but the pulse is the number of beats in a minute so it would be 42x2 and thus her pulse would be 84.
How many folds do you get when you fold 42 pieces of paper?
You get 84 folds if you fold each paper into halves. You get 168 folds if you fold each paper into fourths. How did I figure this out? Well, 42x2(half)=84 folds. Also, 42x4(fourth)= 168 folds> I hope this was the answer you were looking for.
Is 84 prime composite or neither?
84 is composite because it factors are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28,42, 84
What is the correct factorization of 84?
There are many possible factorisations of 84 e.g. 42x2, 21x4, 2x3x14, etc. The prime factorisation of 84 is 2^2 x 3 x 7.
How can you check if a line and a circle intersect?
Okay, so you simply plug the equation of the line into the equation of the circle.(The reason you do this is because whenever they intersect, their x and y values are equal)I'll give an example.Say, for instance, you want to know if y=x+1 (the line) intersects with x2+y2=4 (the circle)Plug in the x+1 for the y in the circle.So you now have:x2+(x+1)2=4(Make sure that you include the parenthesis!)x2+(x+1)(x+1)=4x2+x2+2x+1=42x2+2x+1=42x2+2x-3=0Then you will use part of the quadratic formula, which is:x=(-b±√(b2-4ac))/2aFor this problem, you're interested in what the value under the radical sign is.(b2-4ac)Plug in the numbers22-(4)(2)(-3)4-(-24)4+2428When you plug in the numbers for b2-4ac (known as the discriminant)If the final result is:Greater than 0 - you have 2 intersection pointsEqual to 0 - you have 1 intersection pointLess than 0 - they do not intersectSo, for your original question, if the discriminant ends up being equal to or greater than 0, then the line and the circle intersect.I hope that made sense.
