Answer 2

Answer:

Step-by-step explanation:

1.

we first have to solve this equation

4(3+7)

12+28

=40

A.4(7+3)

28+12

=40 is correct because it is using distributive property and matches the equation

B.4 times 3 plus 7

12+7

=19

C. 4 times (7 times 3)

already wrong because you don't put a times symbol in front of the parenthesis

D4 times 3 plus 4 times 7

12+28

=40

2. B is correct because

55+22=77

11(5+2)

55+22=77

3)12+90=102

A3(4+30)

12+90=102

B4(3+15)

=60

C6(2+15)

12+90=102

12(1+8)

12+96

=108

A and c are the answers
