Answer:
<u>13.2 centimeters</u>
Step-by-step explanation:
<u>Finding the missing side</u>
- (?)² + (9)² = (16)²
- ?² + 81 = 256
- ?² = 175
- ? = √175
- ? = <u>13.2 centimeters</u>
 
        
                    
             
        
        
        
Answer:
C
Step-by-step explanation:
To find the slope between any two points, we can use the slope formula: 

Where (x₁, y₁) and (x₂, y₂) are two, separate points. 
We have the two points (-3, 3) and (-1, -1). 
So, let (-3, 3) be (x₁, y₁) and let (-1, -1) be (x₂, y₂). 
Substitute them into the slope formula to get: 

Subtract: 

Hence, our slope is -2. 
So, our answer is C. 
 
        
                    
             
        
        
        
A/3=7/10
21=10a
a=2.1
100a=100*2.1=210
