Answer:
10
Step-by-step explanation:
You can see that both triangles are the same except for one thing: one is smaller. Since 7 is half of 14 and both triangles are similar, x stands for 10. That is because 10 is half of 20! :D
This is a simple differentiation problem. Let's start by taking the derivative of both sides (with respect to x):

Simplify:

Solve for dy/dx:

Now, plug in the given points:

Further simplification gives:

So,
your answer is 11/23 or
B.
Answer:
did it
Step-by-step explanation:
The line is parallel to the bisector of the 1st and 3rd quadrants

except it is shifted down 2 units:

Since we're considering the area below the graph (not included), the inequality is

Answer:
each side of the hexagon measures 40 cm (which agrees with answer B)
Step-by-step explanation:
Recall that a regular hexagon has six equal sides, therefore, each side would be one sixth of the 240 cm:
each side of the hexagon = 240 cm / 6 = 40 cm
