Answer: 52.5 units squared
Step-by-step explanation:
The formula to find the area of a trapezoid is, (base1 + base2)/2 * height
So you find out which variable is which
Base 1 = 4
Base 2 = 3
Height = 15
Then plug it into the formula,
(4+3)/2 * 15
Then solve the order of operations
7/2 * 15
3.5 * 15
52.5 is the answer
 
        
                    
             
        
        
        
It is either 400 or negative 400 because if you devide 12 by .03 it is 400
        
                    
             
        
        
        
Answer:
1/9x - y = -5
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define equation</u>
Slope-Intercept Form:   y = 1/9x + 5
<u>Step 2: Find Standard Form</u>
- Subtract 1/9x on both sides:                    -1/9x + y = 5
- Multiply -1 on both sides:                         1/9x - y = -5
