Answer:
7^2/x^2-2 for x =3
49/9-2
49/7
7
answer is 7
Step-by-step explanation:
To combine like terms, check if there are any terms just like the first one, and we see 6xy. 9xy + 6xy = 15xy. So that is one term. Now I would see if the second term has any terms like the first one, and we see -3y. So -3y + (-3y), we would get -6y. That means our polynomial is now 15xy - 6y, and because this has two terms, it is a binomial. Hope this helps. Please rate, leave a thanks, and mark a brainliest answer. (Not necessarily mine). Thanks, it really helps!

Answer:
65536 mold spores
Step-by-step explanation:
After 3 hours , 4² mold spores are growing.
After 6 hours , 4³ mold spores are growing.
After 9 hours , 4⁴ mold spores are growing.
After 12 hours , 4⁵ mold spores are growing.
It means in every 3 hours , 4 new spores form and grow from each pre-existing spore.
⇒ After 15 hours , 4⁶ mold spores are growing.
⇒ After 18 hours , 4⁷ mold spores are growing.
⇒ After 21 hours , 4⁸ = 65536 mold spores are growing
