Answer:

No

Step-by-step explanation:

Formula is a squared + b squared = c squared

12 times 12 = 144

7 times 7 = 49

144 + 49 = 193

so 15 times 15 should = 193

but 15 times 15 = 225

Answer:

This triangle is not a right triangle

Step-by-step explanation:

If it were a right triangle, then the pythagorean theorum would work

a^2 + b^2 = c^2

12^2 + 7^2 = 15^2

144 + 49 = 225

This is not true because 144+49=193, not 225

So this triangle is not a right triangle

Eduardwww [97]

Answer:

The total number of cups in arranged in an hexagonal area = 19 cups

Step-by-step explanation:

The pack the most circles within an area, the arrangement with the densest packing is the hexagonal lattice structure similar to the bee's honeycomb as has been proved Gauss and Fejes Toth.

Therefore, we pack the circles in an hexagonal lattice structure in an assumed hexagonal area where we have;

The longest straight line is five cups the next on either side are four cups and the final line on either side has three cups

The total number of cups = 3 + 4 + 5 + 4 + 3 = 19 cups

The total number of cups = 19 cups.
