Hey Roshni, good to see you again. Here's how to solve question 9: Step 1: Evaluate the given expressions. For expression a): 73 - 14 + 1 = 59 + 1 = 60 For expression b): 73 - 14 - 1 = 59 - 1 = 58 Step 2: Evaluate each of the options. For option (a) 73 - (14 + 1): 73 - (15) = 58 For option (b) 73 - (14 - 1): 73 - (13) = 60 For option (c) 73 + (-14 + 1): 73 + (-13) = 73 - 13 = 60 For option (d) 73 + (-14 - 1): 73 + (-15) = 73 - 15 = 58 Step 3: Identify the expressions that are equal. Expression a) 73 - 14 + 1 = 60. This is equal to options (b) and (c). Expression b) 73 - 14 - 1 = 58. This is equal to options (a) and (d). The expressions are: For 73 - 14 + 1: Options (b) 73 - (14 - 1) and (c) 73 + (-14 + 1) For 73 - 14 - 1: Options (a) 73 - (14 + 1) and (d) 73 + (-14 - 1) Send me the next one 📸
