Let a, b, c, and d be non-zero real numbers. If the quadratic equation ax(cx + d) = -b(cx+d) is solved for x, which of the follo

LiRa [457]

Answer:

Option d

Step-by-step explanation:

given that a, b, c, and d be non-zero real numbers.

$ax(cx + d) = -b(cx+d) \\acx^2+x(ad+bc)+bd =0$

we can factorise this equation by grouping

$(acx^2+xad)+)xbc+bd) =0\\ax(cx+d) +b(cx+d) =0\\(ax+b)(cx+d) =0$

Equate each factor to 0 to get

$x=\frac{-b}{a} , \frac{-d}{c}$

Ratio of one solution to another would be

$\frac{-b}{a} / \frac{-d}{c} \\=\frac{ad}{bc}$

So ratio would be ad/bc

Out of the four options given, option d is equal to this

So option d is right

Answer:

21,800 milliliters

Step-by-step explanation:

Here's a trick.

King Henry Died By Drinking Chocolate Milk.

King = Kilo, Henry = Hecto, Died = Deka, By = Base (liters, grams, meters), Drinking = Deci, Chocolate = Centi, Milk = Milli.

This helps to remember the order so you can move the decimal over the proper amount of times.

If you are starting at the base, and need to move to milli, you will move the decimal place 3 places to the right.

So for 21.8 liters = 21,800 milliliters
