Order of Operations:
1. Parentheses
2. Exponents
3. Multiplication
4. Division
5. Addition
6. Subtraction
Step-By-Step Explanation:
1. Take 9 • 11 = 99
2. Take 10 / 2 = 5
3. Take 2 + 10 - 99 = -87
So -87 would be your final answer. Hope that helped!

Step-by-step explanation:
Answer:
x=1
Step-by-step explanation:
5x + 2 = 3x + 4(2x - 1)
Distribute the 4
5x + 2 = 3x + 8x - 4
Combine like terms
5x + 2 = 11x - 4
Subtract 5x from each side
5x -5x + 2 = 11x - 5x - 4
2 = 6x-4
Add 4 to each side
2+4 = 6x-4+4
6 = 6x
Divide each side by 6
6/6 =6x/6
1= x
quadratic formula:
x = <u>-b ± √(b² - 4ac)</u>
2a
7x² - x = 7
subtract 7 from both sides:
7x² - x - 7 = 0
plug values into the quadratic formula:
x = <u>-(-1) ± √((-1)²- 4(7)(-7))</u>
2(7)
simplify:
x = <u>1 ± √(197)</u>

46.5cm squared I believe
Hope this helped ;)
