Figure A and figure B are both regular polygons. The sum of the perimeter of figure A and the perimeter of figure B is 63 inches. The equation 3x + 6y = 63 represents this situation, where x is the number of sides of figure A and y is the number of sides of figure B. Which statement is the best interpretation of 6 in this context?
AThe number of sides of figure B is 6.
BEach side of figure A has a length of 6 inches.
CThe number of sides of figure A is 6.
DEach side of figure B has a length of 6 inches.
Answer & Solution
Correct answer: D. Each side of figure B has a length of 6 inches.
3x is the perimeter of A (3 per side, x sides). 6y is the perimeter of B (6 per side, y sides). So the coefficient 6 represents the length of each side of figure B.
