A metallurgist is making an alloy that consists of 864g of chromium and 4.52 kg of iron find the total mass of mixture in kg

Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol

Ateacher wanted to buy a chair, a bookshelf, two tables and a desk. she spent $900 for all five items and the chair and the desk combined 70% of her total. if the bookshelf cost $50, how much did each of the tables cost?

How do you write 600 as a product of its prime factors (index! )
