True [87]

Answer:

<u><em>A</em></u>

Step-by-step explanation:

<u>a)</u>

<u></u> $(8(3)^{2} / 9) * 7$ <u></u>

<u>8(9) / 9 = 8 x 7 = 56</u>

b)

$2(3)^{2} * 3 - 4(3)$

2(9) * 3 - 12

18 * 3 = 54 - 12 = 42

c)

$4(3)^{2} - 6(3) + 12$

4(9) - 18 + 12

36 - 18 = 18 + 12 = 30

d)

$7(3) + (3 * 8)$

21 + 24 = 45
