C.
(6 × 5)(6 × 2)

Answer 1

[A] 6 (5+2)

Explanation:

Solve each answer choice:

[A] 6(5+2) = 30+12 [True] [6*5=30 and 6*2 = 12.. So 30+12]

[B] (6+5)(6+2)=11 * 8 [False] [6+5 =11 and 6+2=8.. 11*8]

[C] (6*5) (6*2)= 30 * 12 [False] [6*5=30 and 6*2 = 12]

Hence, [A] 6(5+2) is the correct Answer .

We can also find the answer by finding all the solutions:

30 + 12 = 42

[A] 6(5+2) = 30+12 = 42

[B] (6+5)(6+2)=11 * 8=88

[C] (6*5) (6*2)= 30 * 12 = 360
