This is a parallelogram which means the two opposites sides are equal. Then, we can solve the problem as shown below:
mAB = m DC
9x -14 = 3x + 4
Transpose and combine same term:
9x - 3x =4 +14
6x= 18
x=3
Solving for DC:
DC = 3X + 4
DC = 3(3) + 4
DC = 13 units.
The answer is 13.

Step-by-step explanation: Answer is A
Answer:
y = 2.4
Step-by-step explanation:
If y varies inversely as x, it means there's an inverse relationship between y and x, that is if x is increasing, y is decreasing and vice versa. In such instance, we have to find the constant of proportionality "k"
Hence,
y~1/x
y=k/x
When y =-6 and x =-2, we insert these values to find the value of the constant "k"
-6 = k/-2
k = 12.
Using this value of k to determine value of y when x =5 becomes:
y = 12/5
y = 2.4
The given expression, 81a^6 - 100, is a difference of two squares. The first term 81a^6 is a square of 9a³. The second term, 100, is a square of 10. The factors of the given expression is therefore, (9a³ - 10) x (9a³ + 10).
