The least common denominator is 1.
2 is the correct answer I'm almost definite

It took 32.4 minutes for the battery to be fully charged.
Step-by-step explanation:
A) 17/52
B) 15/26
C) 4/13
A) The probability of getting a club is 13/52; the probability of getting a 3 is 4/52; the probability of a club or 3 is
13/52+4/52 = 17/52
B) The probability of a red card is 26/52; the probability of a King is 4/52; the probability of a red card or King is
26/52+4/52=30/52 = 15/26
C) The probability of a 9 is 4/52; the probability of a face card is 12/52; the probability of a 9 or a face card is 4/52+12/52 = 16/52 = 4/13
Your surface area is: S=x^2+4xh=84 square inches and h=2 inches; so you get:
x^2+(4×2)x=84
x^2+8x-84=0 qhich is a quadratic equation. Using the quadratic formula you get two results for x:
x1=-14 and x2=6
choose the second (positive)
