Hello! So, you use 120 pieces of fabric. You could not use all 120 pieces, because you can not make a square. The most you could use to make a square is 100. That would be 10 squares a row, with a side length of 6, which would make a perimeter of 60. Then, the other side would be 60. So 60 * 60 is 3600. The area of the blanket is 3600 square inches.
Area of square = x^2
Area of rectangle = xy
Let x = side of square
Let x + 3 = width of rectangle
Let x + 5 = length of rectangle = y
Here is the set up:
x^2 + (x + 3)(x + 5) = 249
You finish.
The probability that the fourth digit is 4 is 1/6.
<h3>What is the probability?</h3>
Probability is used to calculate the odds that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
Probability the number is 4 = 1 / possible numbers
Possible numbers = 4, 5, 6, 7, 8, 9,
= 1/6

Answer:
Step-by-step explanation:
There are no solutions. The slopes of both lines are the same so they are parallel: they will never intersect. Therefore, there cannot be a solution.

Answer:
x = 36 and √x = 6; total 42 children
Step-by-step explanation:
Number of boys: x
Number of girls: √x
Total number of kids: x + √x = 42.
Find x.
Rewrite x + √x = 42 as √x = 42 - x. Then square both sides:
x = 1764 - 84x + x^2, or
x^2 - 85x + 1764 = 0
Check out Answer C: x = 36. Is the above equation true for x = 36? YES
Check out Answer A: x = 49. Is the above equation true for x = 49? YES
Assume that x = 36. This would be the number of boys. The number of girls would be √36, or 6. Does the sum of 36 and 6 equal 42? YES. So the number of boys is 36 and the number of girls is 6.
Assume that x = 49. This would be the number of boys. The number of girls would be √49, or 8. Does the sum of 49 and 7 equal 42? NO. So we reject x = 49 as the number of boys and accept x = 36 as being correct.
