Perimeter is when you add up all the sides of a shape. For Anthony's shape, it would be 6 time 5, or 30 inches. For Carol's shape, it would be 6 times 5, or 30. Both shapes have the same perimeter. Hopefully this helps, let me know if you have any more questions.
The answer is D. If you make a right triangle with the line, then you can use the Pythagorean theorem (a^2+b^2=c^2) to solve for VW. The vertical line would be 4 units and horizontal line would be 2 units. Therefore 4^2+2^2=20 take the square root of 20 and that is the answer.
Answer:
9
Step-by-step explanation:
K^2 - 2(9)k + 9^2
Or
k^2 - 18k + 81
Just sub in k for a and 9 for b.
