Answer 1

7×13-7×2=77

18×9-18x7=36

5×23-25×10=-135

25×13-25×10=75

Answer 2

Sure, let's solve these expressions step by step:

1. 7 × 13 - 7 × 2 = 91 - 14 = 77

2. 18 × 9 - 18 × 7 = 162 - 126 = 36

3. 5 × 23 - 25 × 10 = 115 - 250 = -135

4. 25 × 13 - 25 × 10 = 325 - 250 = 75

The answers to the expressions are:

1. 7 × 13 - 7 × 2 = 77
2. 18 × 9 - 18 × 7 = 36
3. 5 × 23 - 25 × 10 = -135
4. 25 × 13 - 25 × 10 = 75
