3025 is a perfect square, so just take the square root.
sqrt(3025) = 55
If it is 76 feet LOWER than 73 above sea level, then you must do
73-76= -3
So Mudville is 3 feet BELOW sea level.
The roots of this equation are 1 and -1. You can get this by factoring to the version below.
(x + 1)(x - 1)
Answer:
The area of 6 KM and 6 KM is 36 KM (kilometers).
With finding the data that falls below a percentage, you need to look closely at the words.
Notice that it said 25% of... that word "of" means to multiply. But, what are you multiplying? Well, if you look more closely at the plot, you'll see that your dot and line is lying on 58. But make sure you put 25 over 100.
So, your equation would be set up like this: 58 ÷ x = 100/25
We're using "x" as our way of saying, "We need to find out this number."
After that, we'll need to multiply both sides of the equation by "x"
(58 ÷ x) × x = (100/25) × x
Now that you have your equation, you'll need to divide both sides by 4 to get "x".
x = 4 ÷ 58
58 ÷ 4 = 14.5
Your answer is 14.5 of the data that falls below the number.
