Answer:
C
Step-by-step explanation:
Calculate AB using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(- 1, - 3) and (x₂, y₂ ) = B(11, - 8), thus
AB =
=
= = = 13 → C
Any number from 21-98 is between 20 and 99.
Let the two consecutive even integers be x and x+2.
Then x^2 = (x+2) + 10
Simplifying, x^2-x -2 - 10 = 0, or x^2 - x - 12 = 0. Factoring,
(x-4)(x+3) = 0. Solving for x: x=4 and x= -3.
If the first number is x = 4, then the second is x+2=4+2=6.
But wait! If the first number is -3, then the second is x+2 = -3+2 = -1.

Answer:14 days 14hours 17min 8 sec
Step-by-step explanation:
14×14=196
Then the 4 extre hours divide them in the 14days
4×60=240min
240÷14=17min and extre 2min
2min×60=120 sec
120sec÷14=8 sec
