Answer:
the third one
Step-by-step explanation:
the square root of 25 is 5. 5+2 = 7.
this is a rational number (the set of all integers and fractions).
the other 2 portions contain at least one element that is not rational. and so the sum with such a number is not rational.
45 and 7 are no square numbers, and therefore the square root of these numbers contains a neverending chain of digits after the decimal point without having any repeating pattern. these are real numbers but not rational numbers.
The correct answer is C. Commutative Property
Answer:
x = 99
Step-by-step explanation:
<u>Step 1: Solve for x</u>
-12 + x/11 + 12 = -3 + 12
x/11 * 11 = 9 * 11
x = 99
Answer: x = 99
other leg = 12 cm
using Pythagoras' identity with x as the side to be found, then
x = √(13² - 5² ) = √(169 - 25 ) =√144 = 12
