Negative multiply negative = Positive
Negative multiply positive = negative

Thus the answer is -4a + 16b - 12c - 12d.
Answer:
t = -24*log(2/3)
Step-by-step explanation:
The expression is:
V = 22,500*10^(-t/12)
Replacing with V = 10,000 and isolating t, we get:
10,000 = 22,500*10^(-t/12)
10,000/22,500 = 10^(-t/12)
4/9 = 10^(-t/12)
(2/3)² = 10^(-t/12)
2*log(2/3) = -t/12
-12*2*log(2/3) = t
t = -24*log(2/3)

You can draw vertical line, and get 2 rectangles.
1) First one with sides 2 and 7.
2) Second one with sides 1 and (5-2) = 3, 1 and 3.
3) Area of the first one =2*7=14 units²
4)Area of the second one = 1*3=3 units²
5) Area of the whole polygon = 14+3=17 units²
Answer C. 17units².
