x² - x + 4
General Formulas and Concepts:
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
(4x² - 2x - 3) + (-3x² + x + 7)
<u>Step 2: Simplify</u>
- Combine like terms (x²): x² - 2x - 3 + x + 7
- Combine like terms (x): x² - x - 3 + 7
- Combine like terms (Z): x² - x + 4
Answer:
72%
Step-by-step explanation:
Because you add 10 and 4 to get 14.
Next minuse 14 from 50 to get 36.
Then divide 36 and 50 to get 0.72.
Finaly move your decimal to get your percent

Answer:
I believe it's 65 degrees.. I'm sry if wrong I may have fell asleep too
Step-by-step explanation:
we know that
In a quadratic equation of the form 
the discriminant is equal to
if 
-------> the equation has two real number solutions
if 
-------> the equation has one real number solution
if 
-------> the equation has two complex number solutions
In this problem we have
so
substitute in the formula
----> the equation has two real number solutions
therefore
<u>the answer is</u>
the equation has two real number solutions
