Answer:

  • 35 feet long
  • 25 feet wide

Step-by-step explanation:

Let w represent the width of the garden. Then the width of the garden and walk together will be w+6. The length of the garden is described as w+10, so the length with the walk is w+16.

The difference in areas with and without the walk is 396 square feet:

  (w+6)(w+16) -(w)(w+10) = 396

  w² +22w +96 -(w² +10w) = 396 . . . . expand products

  12w = 300 . . . . . . collect terms, subtract 96

  w = 25 . . . . . . . . . divide by 12

The dimensions of the garden are 25 feet wide by 35 feet long.

Based on the random sample of beach lengths taken, the probability of a randomly selected beach having a length of 12 miles is C. 0.

<h3>What is the probability that a beach is 12 miles in length?</h3>

Beach length is considered a continuous variable which takes a numerically positive form because it can have any one of infinite possible values.

As a result, there is no possibility that a beach chosen at random will have a given length of 12 miles which means that the probability is 0.

In conclusion, the probability that a selected beach has a length of 12 miles is 0.

Exponent Practice:<br> x^2/3=64
docker41 [41]
X^2/3 = 64
x^{2} =64^{3}
x = 64^{3/2}

it is easier to first find square root of 64 and than power it to 3
square root of 64 is 8 which means our equation now looks like:
x = 8^3
now the answer is after powering 8 to 3:
x = 512
