Let x,y and z three real numbers. write an algebraic expression to denote the product of z,x and y

The product of x, y and z would be x*y*z or we can simply write xyz without the asterisks. A product is the result of multiplying two or more numbers.

The order of multiplication does not matter. Example: 2*5 = 10 and 5*2 = 10

  sides are proportional and angles are congruent

Step-by-step explanation:

Every segment in ABCDEFG is parallel to, and double the length of, the corresponding segment in HIJKLMN. All corresponding angles are congruent. Thus, the definition of similar polygons is met:
