What are the zeroes of f(x) = x^2 + 5^x + 6?
1 answer:
You can factor it by using a method of your choice. I'll just use guess and check, because it's the easiest in this situation (for me). I need two numbers that multiply to 6, and add up to 5. Those two number are 2 and 3. 2 * 3 = 6, and 2 + 3 = 5. So, I can write the above equation as follows in factored form:
Then it's pretty easy to recognize the zeros because I just have to solve for each parentheses by doing this:
and
So, your zeros are at -2 and -3. Your answer is A. If any step doesn't make sense, hmu!

The ratio is 2 : 9
Step-by-step explanation:
Given:
The number of sports store = 4
The number of clothing store = 9
The number of jewellery stores = 5
To Find :
The ratio of number of sports stores to the total number of stores
Solution:
The ratio of number of sports stores to the total number of stores
=
The total number of stores = number of sports store + number of clothing store + number of jewellery store
The total number of stores = 4 + 9 + 5
The total number of stores = 18
Now the ratio is
= or 4 : 8
The ratio after reduction is
= or 2 : 9 or 2 to 9
