Answer:
A
Step-by-step explanation:
12x² - 7y² - 10x² + y² = 12x² - 10x² - 7y² + y²
= (12 - 10)x² + (-7 + 1)y²
= 2x² + (-6y²)
= 2x² - 6y²
17/97 to decimal
17/ 97 = 0.175
Answer : 0.175
..
here's your solution,
A (5, 4) and B (5,-2) = 6 units
E (-2,-1) and F (-2,-5) = 4 units
C (-4,1) and D (1,1) = 5 units
G (3,-5) and H (6,-5) = 3 units
