Please hurry I have to submit this by 3:00

Answer 1

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
