Answer:
AB = 5 units
BC = 5 units
AC = or about 6.4 units
Step-by-step explanation:
distance formula: square root of the sum of the difference of the y-values and the difference of the x-values
ex, dAB = √(4-0)² + (3-0)²
= √16 + 9
= √25
= 5
the answer would be 18cm
length x width
y= -3.6
-9.5(1.4)-2.5y=-4.3
-13.3-2.5y=-4.3
-9=2.5y
y=-3.6
