Use Pythagoras (x^2 + y^2 = r^2)
Simplified: leg squared plus leg squared equals hypotenuse squared.
Therefore 4^2 + 6^2 = h^2
16+36=h^2
h^2 = 52
H= root of 52=7,21 inches
The answer to the question is -24.
What you meant was the "commutative" property.
So we can say that when adding:
<em>"<u>Commutative</u> means that the order does not make any difference in the result."</em>
Example:
5 + 6 = 6 + 5
a + b = b + a
The commutative property does not hold for subtraction.
Example:
4 - 1 ≠ 1 - 4
a - b ≠ b - a
Ok, now does the commutative property hold true for multiplication?
2 x 3 = 3 x 2
2 x 3 x 4 = 4 x 3 x 2
Yes.
What about division?
12 ÷ 4 ≠ 4 ÷ 12
The commutative property does not hold for division.
Also known as a recurring decimal, a repeating decimal is a number that has repeating digits infinitely, can also be identified with a line over the last number of the decimal.
