Step-by-step explanation: Commutative property:
For multiplication: x ∙ y = y ∙ x
Example 1:
For addition: x + y = y + x
Example 2:
Notice that numbers don’t commute under the operation of subtraction
Answer:
Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are in proportion, that is
=
, substitute values
=
=
( cross- multiply )
2x = 12 ( divide both sides by 2 )
x = 6
