- The commutative property is a number property where the answer obtained is the same no matter the position of the numbers you are multiplying together.
- Commutative property of multiplication is expressed as:
a x b = b x a
a x b x c = a x c x b = b x c x a
- Note: " . " in the question also means "x" (multiplication)
- Applying commutative property to the question:
(7/15)⋅(−11)⋅(30)
(7/15) ⋅ (−11) ⋅ (30) = (7/15) . (30) . (11)
The values interchanged are: 11 and 30. The result of the multiplication remains unchanged.
Option A is the correct answer.

Answer:
idkim only 11
Step-by-step explanation:
Answer:
Below.
Step-by-step explanation:
( 1 + sin a) / (1 + csc a)
= (1 + sin a ) /( 1 + 1/ sin a)
= ( 1 + sin a) / (sin a + 1)/ (sin a)
= (sin a(1 + sin a)) / (1 + sin a)
= sin a.
tan a / sec a
= (sin a / cos a) / (1 /cos a)
= (sin a cos a) / cos a
= sin a
The two expressions are both equal to sin a:
Therefore
(1 + sin a) /( 1 + csc a) = tan a / sec a.
it's 21/21 which would simplify to 1
How I got that answer was by multiplying 3/7 and 7/3 to get 21 both times
Answer:
n = 6
Step-by-step explanation:
Since the triangles are similar then the ratio of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
6n = 36 ( divide both sides by 6 )
n = 6
