For this case we have that the complete question is:
A spider ate 25% more bugs this month than last month. The spider ate 8 bugs last month. How many bugs did the spider eat this month?
So, we propose a rule of three:
8 bugs -----------> 100%
x -----------------------> 25%
Where the variable "x" represents the number of bugs equivalent to 25%.
Thus, 2 bugs represent 25%
If this month the spider ate 25% more, then it ate:
Answer:
This month, the spider ate 10 bugs

EXPLANATION
The standard form of a quadratic equation is:
To convert this function to standard form, you follow the steps below:
- Factor 'a' from the variable terms
- Add and subtract the square of half the coefficient of x.
- Factor the perfect squares
- Simplify the constant terms to get the vertex form as
For example:
Given the standard form:
Factor 2 from the variable terms
Add and subtract the square of 3.
Factor the perfect square an simplify
This is the vertex form
