Problem:
Calculate the value of c + d if:
a) c = 10 and d = 25; b) c = 15 cm and d = 45 cm.
Solution Method:
For this type of exercise, simply substitute the given values of c and d into the expression c + d, calculate carefully to find the correct result.
* Note: For questions with units, the result should be written with the corresponding units.
Answer:
a) Substitute values: c = 10 and d = 25, we get c + d = 10 + 25 = 35
b) Substitute values: c = 15 cm and d = 45 cm, we get c + d = 15cm + 45cm = 60cm
