Answer: 1. 7(3+5)= 21+35
2. 15 - 10 = 5 (3-2)
Step-by-step explanation:
1: 7(3+5) = ? + ?
Opening the bracket and multiplying each number by 7
7 x 3 + 7 x 5 = 21 + 35 =56
7(3+5)= 21+35
2.15 - 10 = ? (3-2)
15- 10 = 5 , On the other hand,
3-2 = 1
to make the left hand equivalent to the right hand side , we multiply the difference gotten from 3-2 by 5 so we have
15 - 10 = 5 (3-2)
5=5(1)
5=5
