Step-by-step explanation:
The communitive property states that if you reverse the order of a multiplication or addition problem you will get the same result.
communitive property examples
x + 2 = 2 + x
xy = yx
Using the Theorem of Pythagoras (a² + b² = c²)
Put in the values:
12² + 12² = 28²
Is it correct? (solve)
Nope! Because 12² + 12² = 288, and the square root of 288 is about 17, not 28.
The answer is no, 12cm, 12cm, 28cm cannot form a triangle.

21x + 28 = 156 - 2
21x = 154 - 28
21x/21 = 126/21
X = 6
