$(4a+7b-12c)-(8a-9b+12d)\\4a+7b-12c-8a+9b-12d$

Negative multiply negative = Positive

Negative multiply positive = negative

$-8a+4a+9b+7b-12c-12d\\-4a+16b-12c-12d$

Thus the answer is -4a + 16b - 12c - 12d.

The options seem a bit mis-formatted but here is the way p is computed:

the decrease is 2000-1600

and it is relative to: 2000 (2003 attendance)

so $p=100 \frac{2000-1600}{2000} = 100 \frac{400}{2000}$

and so that aligns with your Option A. Options B, C, D look incorrect for sure.

Answer:

x = 0.96

Step-by-step explanation:

$7 \times 16^{8x - 8} = 3$

$(2^4)^8(x - 1) = \dfrac{3}{7}$

$2^{32(x - 1)} = \dfrac{3}{7}$

$\log 2^{32(x - 1)} = \log \dfrac{3}{7}$

$32(x - 1)\log 2 = \log 3 - \log 7$

$(x - 1) = \dfrac{\log 3 - \log 7}{32}$

$(x - 1) = \dfrac{\log 3 - \log 7}{32\log 2}$

$x = \dfrac{\log 3 - \log 7}{32\log 2} + 1$

$x = 0.961800237...$

Answer: x = 0.96
