Since 16 and 25 are perfect squares you can factor the first part.
4^2-5^2(b+3)^2
=(4-5(b+3))(4+5(b+3))
=(4-5b-15)(4+5b+15)
=(-11-5b)(19+5b)
Which can be expanded if necessary,
= -209+150b-25b^2
If i’m correct it’s y=2 im 99% sure
Hey friend!
Let's work this out.
The answer is 2.5r
The probability would be three over 6 in fraction form, which, simplified, is a 50% chance. Hope this helps!
