Factor 6x4 - 5x2 + 12x2 – 10 by grouping. What is the resulting expression? O (6x + 5)(x2 - 2) O (6x - 5)(x2 + 2) (6x2 + 5)(x - 2) (6x2 - 5)(x2 + 2) ​

()()

Step-by-step explanation:

Always arrange in descending powers first.  In this case that is already done.

Try grouping the first two terms and the last two terms first

  Factor out the GCF of both groups

    Note that is a factor in each group. That's    

                                           good

Now treat as a GCF and you get

()()

Since    and    are both prime, we are finished.  

You can check to see if you are correct by FOILing the answer you got.  OK?

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

7

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7
