Answer:
c = -18
Step-by-step explanation:
We need to distribute the -3 to each term within the parentheses. This essentially means finding the sum of the product of -3 with each of those inner terms:
-3 * c + (-3) * 14 + 3 = 15
-3c - 42 + 3 = 15
-3c = 15 + 42 - 3 = 54
c = 54/(-3) = -18
c = -18

To estimate the unit rate, we should round the 5.79 to 6. This makes it much simpler to solve as 6 is a multiple of 12. The unit rate, in this case, is the price of 1 pair of socks. We can find this by dividing both the price and pairs of socks by 12. When we do this, we can see that each pair of socks is approximately $0.50.
Answer:
16 * √3 cm² or approximately 27.71 cm²
Step-by-step explanation:
Given the 8 cm length of the diagonal and the 30° (π/6 radians) angle with one of the sides, we can calculate the width and height of the rectangle using:
8 * cos(π/6) = 8 * ((√3)/2) = 4 * √3
8 * sin(π/6) = 8 * (1/2) = 4
Multiply those two values together to get the area and you get
16 * √3 cm²
