It seems like you've begun to group and factored out the GCF.
Because the inner binomials (the ones in parentheses) are the same, the next step is to rewrite the equation like so:
(25-x^2)(y+1)
From here, we can further factor (25-x^2) since they are both perfect squares.
(5+x)(5-x)(y+1)
No further terms can be factored so that is the final answer. Hope this helps!
For this, we will be using dimensional analysis as such:

In short, 24,900 miles is 40,072,665.6 (40,072,666 if rounded to the whole meter) meters.
First w have to figure out the solution o the right side of the equation
So (insert long line here) = 8+32
We simplify it
(Insert long line here) = 40
So, you hen ask yourself what options are equal to 40 ( which is the second option)
Option b
Numbers 41,378 or words forty one thousand three hundred seventy eight
