She started with x books. She purchased 3 more.
Add the two amounts (x and 3) to find out the number of books she has now.
Now she has x + 3 books.
We are told she now has 11 books, so x + 3 must equal 11.
The equation is x + 3 = 11
Answer: C.) x + 3 = 11
Answer:
65 degrees
Step-by-step explanation:
First you must distribute the 2x to the numbers inside the parentheses
(2x * x) + (2x * -1) = 3
- 2x = 3
To make this a quadratic equation you can solve bring the 3 over to the left side of the equation by subtracting it to both sides
- 2x - 3 = 0
Use the quadratic equation to solve this (image of the quadratic equation is below)
Remember that quadratic functions are set up like so:
That means that in this equation...
a = 2
b = -2
c = -3
^^^Plug these numbers into the quadratic equation and solve...
Keep in mind that +/- is ±
