Question

Two circles have circumferences of (8xy) cm and (5xy) cm respectively. what is the variable expression to represent the sum of their circumferences?

(8xy)cm X (5xy)cm
(8xy)cm - (5xy)cm
(8xy)cm + (5xy)cm
(8xy)cm divided by (5xy)cm

Answer 1

Answer:the variable expression to represent the sum of their circumferences would be

(8xy)cm + (5xy)cm

Explanation:

The circumference of the first circle is 8xy cm

The circumference of the second circle is 5xy cm

the variable expression to represent the sum of their circumferences would be

(8xy)cm + (5xy)cm

This variable expression can also be simplified further because both terms contain xy.
