Answer:
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
