Answer:
Option C is false
It is true that the square of both 10 and -10 is 100 but you can still obtain 100 by squaring 5 so the third option is incorrect
Is there a picture that goes with the problem
280,000 should be recorded in Ritts Roofing's records.
49 cm > 4 dm
because 1 dm = 10 cm
Glad I could help, and good luck!
