Hey there!
9(12 + 7)
= 9.0(12) + 9(7)
= 9(12) + 9(7)
= 108 + 63
= 171
ORIGINAL ANSWER: 171
Option A.
09 + (12 + 7)
= 09 + 12 + 7
= 9 + 12 + 7
= 21 + 7
= 28
Option A. can’t be your answer because
28 ≠ 171
Option B.
(9 + 12) * (9 + 7)
= 9 + 12 * 9 + 7
= 21 * 16
= 336
Option B. can’t be your answer because
336 ≠ 171
Option C.
9 * 12 + 7
= 108 + 7
= 115
Option C. can’t because 115 ≠ 171
Option D.
(9 * 12) + (9 * 7)
= 9 * 12 + 9 * 7
= 108 + 63
= 171

Therefore, your answer is: Option D.
Good luck on your assignment and enjoy your day!
