You have 8 cups of flour to 24 muffins, which can be shown as 8:24, or 8/24. You need to find x cups of flour to 30 muffins, which can be shown as x:30, or x/30. You will want to cross multiply.
8 x
-- * --
24 30
8 * 30 = 24 * x
240 = 24x
10 = x
You need 10 cups of flour.
Answer:
-10x^2-33x+1
Step-by-step explanation:
=>6x(x-4)-16x^2-(9x-1)
multiply 6x with (x-4) and multiply - with (9x-1).
= 6x^2-24x-16x^2-9x+1
arrange the like terms with same powers of x with the respective sign.
= 6x^2-16x^2-24x-9x+1
simplify by using the respective arthematic operations.
= -10x^2-33x+1
