Answer:
25x² − 20x + 4
Explanation:
(5x − 2)²
= (5x + −2)(5x + −2)
= (5x)(5x) + (5x)(−2) + (−2)(5x) + (−2)(−2)
= 25x² − 10x − 10x + 4
= 25x² − 20x + 4

Step-by-step explanation: "T" represents the total amount of money he has left, so T = z [Whatever amount he had to begin with] - 3 [The amount he lost]. Hope that this helps!
Another way to show this equation is with the slope-intercept for of y = x -3
 
        
             
        
        
        
Answer: A
Step-by-step explanation: you have to use the 2 points distance formula that is ✓(xb - xa)^2 + (yb - ya)^2 so ✓(6+6)^2 + (-3-4)^2 = ✓144 + 49 = ✓193
