Answer:
-5
Step-by-step explanation:
You can work backwards with this problem if that helps you.
so, what times 3 = -15
-5 times 3 = -15 so that would be the answer
(-5x^5)(a) = 25x^7 + 100x^5
<u>+5x^5 +5x^5</u>
a = 25x^7
Scientific notation means the numbers have to be between 1 and 10, so here is the answer as well as where to move the decimal
Solution
Problem 6
For this case we can do this:
12, 16,__, 14, 8, 7
We can solve for x like this:
