El número favorito de mi amigo tiene 3 cifras. Si sabemos que los tres dígitos suman 10, el primer dígito es igual a la suma de los otros dos, y que el primero más el segundo equivale al cuádruple del tercero, ¿cuál es ese número?

No he does not because he can only cover 12 square feet from 15 square feet which he will still need 3 more. this is because if 3×5=15 square feet and 15-12=3 which thats the answer

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
