C & D
Step-by-step explanation:
One evident common factor between 60, 90, & 20 is 10 because all these numbers end in a 0; Therefore one way to factor the equation 60y - 90 - 20x is;
10 (6y – 9 – 2x)
5 is also a common factor between the numbers 60, 90, & 20
60/5 = 12; 90/5 = 18; 20/5 = 4
Therefore 60y - 90 - 20x is also equal to;
5 (12y – 18 – 4x)
Answer:
Step-by-step explanation:
Calculate the length (d) using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 1, 3) and (x₂, y₂ ) = (0, 7)
d = 
= 
= 
= ≈ 4.1 ( to 1 dec. place )
Answer: 26 and 46, perhaps
Step-by-step explanation: The question does not state if point b is between a and c. Yes, it stands to reason that b is between a and c, but this is math. Since the question asks for TWO possible answers, it leads me to believe that b could also be prior to point a. Then we have two possible scenarios:
The logical one: A - - - B - - - C BC = (36 - 10) = 26
and this: B - - - A - - - C BC = (36 + 10) = 46
