Answer:
A , B and C
Explanation:
evaluate the expressions following the order of operations as set out in PEMDAS
initial expression
note that • indicates multiplication
3 (2 + 6) + 4 × 5 ← evaluate parenthesis
= 3(8) + 20 = 24 + 20 = 44
A
5 × 4 + 3 × (6 + 2) ← evaluate parenthesis
= 5 × 4 + 3 × 8 ← perform multiplication
= 20 + 24 ← perform addition
= 44
B
(6 + 2) × 3 + 4 × 5 ← evaluate parenthesis
= 8 × 3 + 4 × 5 ← perform multiplication
= 24 + 20 ← perform addition
= 44
C
3 × 2 + 3 × 6 + 4 × 5 ← perform multiplications
= 6 + 18 + 20 ← perform addition
= 44
D
3 × 2 + (6 + 4) × 5 ← evaluate parenthesis
= 3 × 2 + 10 × 5 ← perform multiplication
= 6 + 50 ← perform addition
= 56
the expressions equivalent to the initial expression are A , B and C
