The cost (in dollars) in making b bracelets is represented by 4+5b. the cost (in dollars) of making b necklaces is represented by 8b+6. write a polynomial in standard form that represents how much more it costs to make b necklaces than b bracelets.

Step-by-step explanation:

The cost (in dollars) in making b bracelets is represented is



The cost (in dollars) of making b necklaces is



To find how much more it will cost to make b necklaces than b bracelets, we find the difference,









This is a polynomial in descending powers of b, hence it is in standard form;

Answer d; a supplementary angle = 180°, so if that angle = 150°, y would = 30°.
