Answer:

A triangle has 3 sides: a, b, c satisfying inequalities below:

=> a + b > c > |a - b|

=> b + c > a > |b - c|

=> c + a > b > |c - a|

9, 15, 17 satisfy the inequalities above (you can check it easily).

Hope this helps!

Which expression uses the commutative property of addition and the associative property of multiplication to rewrite the express

musickatia [10]

Step-by-step explanation:

many things are possible.

the only thing we must not do is mixing the addition elements with the multiplication elements.

but we could change the expression to

3×(3×8) + 5

5 + (3×3)×8

5 + (3×8)×3

and so on, and it would always be the same result.
