23 for distance and -18 for displacement between them
Answer:
any four sided closed shape
Step-by-step explanation:
can you add the option?
Answer:
im not exactly sure how to do this one but i think that you can use pythagoras theorem which is a^2 +b^2=c^2. In the question you can use d^2 +e^2= f^2
Answer:
D
Step-by-step explanation:
Just multiple them and see which one fits the question.
A: 10 * 8 = 80 * 9 = 720 So it's too big.
B: 9 * 9 = 81 * 9 = 729. Also too big.
C: 9 * 10 = 90 * 9 = 810 too big.
D: 8 * 8 = 64 * 11= 704
Answer:
Length = 10
Step-by-step explanation:
Normally you would use
d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
But the 2 y values are the same so y2 - y1 = 0.
d then becomes sqrt(x2 - x1)^2
d = (x2 - x1) because the square root of (x2 - x1)^2 is just (x2 - x1)
x2 = 7
x1 = -3
d = (7 - - 3) = 10
