Answer:

C. six

Step-by-step explanation:

A hexagonal prism has 18 edges and a hexagonal pyramid has 12 edges, therefore the difference between the number of edges of the two solids is six (6) because 18-12 is 6.

The word "difference" infers that we need to subtract numbers in order to find how many are left.

Step-by-step explanation:

$2n=2 \times 3\sqrt{2}$

$2n=6\sqrt{2}$

Answer:

b=9,a=12

Step-by-step explanation:

I solved by substitution:

b = 3/4a ---> plug this into the other equation

a + b = 21 is now a + 3/4a = 21

Reduce: 7/4a = 21

a = 12

Now solve for b:

b=3/4a is now b=3/4(12)

b=9
