You might have to go through the list cuz my teacher sometimes changes the order of the questions but good luck!
The answer is (9•12)+(9•7) they both equal 171

Surely you have heard of the distributive property.
Worst case scenario : Why not work out each of the answers, then
compare with the answer to the original question.” Shut up lmfao
Which expression can be written as 9x(12+7)
To determine which expression can be written as 9•(12+7), we need to simplify each option and see if it matches the given expression.
Let's simplify each option:
A) 9+(12+7)
To simplify this expression, we first perform the addition inside the parentheses: 12+7 = 19. Then, we add 9 to 19: 9+19 = 28. So, option A is equivalent to 28, which does not match the original expression of 9•(12+7).
B) (9+12)•(9+7)
To simplify this expression, we first perform the additions inside the parentheses: 9+12 = 21 and 9+7 = 16. Then, we multiply 21 by 16: 21•16 = 336. So, option B is equivalent to 336, which does not match the original expression of 9•(12+7).
C) 9•12+7
To simplify this expression, we first perform the multiplication: 9•12 = 108. Then, we add 7 to 108: 108+7 = 115. So, option C is equivalent to 115, which does not match the original expression of 9•(12+7).
D) (9•12)+(9•7)
To simplify this expression, we first perform the multiplications: 9•12 = 108 and 9•7 = 63. Then, we add 108 to 63: 108+63 = 171. So, option D is equivalent to 171, which matches the original expression of 9•(12+7).
Therefore, the correct answer is D) (9•12)+(9•7).
