Answer:
22 ft by 18 ft
Step-by-step explanation:
Area = l * w
Area = (x+8) * (x+4) = x^2 +12x+32
396 = x^2 +12x+32
400 = (x+6)^2
20 = x+6
x = 14
x+8 = 22
x+4 = 18
Answer:
40 + 38w ≥ 265.49
Where “w” represents the amount
of weeks it will take to

Answer:
8/15
Step-by-step explanation:
The balls are numbered 3 through 17, so there are 17 − 3 + 1 = 15 balls. 8 of them are odd and 7 of them are even.
So the probability of an odd numbered ball (which includes the number 11 ball) is 8/15.
