First we do brackets 
(8900)-(1x89)
next we do the next bracket
8900-89
now we finish the equation
8811

<u>Algebra I</u>
- Coordinates (x, y)
- Slope Formula:  
Step-by-step explanation:
<u>Step 1: Define</u>
Point (2, 5)
Point (-3, 7)
<u>Step 2: Identify</u>
x₁ = 2, y₁ = 5
x₂ = -3, y₂ = 7
<u>Step 3: Find slope </u><em><u>m</u></em>
Simply plug in the 2 coordinates into the slope formula to find slope<em> m</em>
- Substitute in points [Slope Formula]:                                                              
- [Slope] [Fraction] Subtract:                                                                              
- [Slope] [Fraction] Rewrite:                                                                               
 
        
             
        
        
        
A cross section is the shape we get when cutting straight through an object. The cross section of this object is a triangle. It is like a view into the inside of something made by cutting through it.
        
             
        
        
        
Yes the mean is the middle number so go according to the order from smallest to biggest 48 is the middle number
