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

A student makes a $10.50 purchase at the bookstore with a $20 bill. The store has no bills and gives the change in quarters an

Leviafan [203]

Answer: he collected 22 quarters and 8 fifty-cent pieces

Step-by-step explanation:

Given;

The total amount of money he is to collect is;

A = 20 - 10.50 = $9.50

Let x represent the number of quarter he collected.

Then the number of fifty-cent pieces he collected will be; 30-x

Therefore we can represent it with the equation below;

0.25x + 0.50(30-x) = 9.50

0.25x + 15 - 0.50x = 9.50

0.25x = 15-9.50

x = (15-9.50)/0.25

x = 5.50/0.25

x = 22

The number of fifty-cent is equal to;

30-x = 30-22 = 8

Therefore, he collected 22 quarters and 8 fifty-cent pieces

The cirum ference of cylinder is 44cm and height is 7 cm find its curved surface area

Eva8 [605]

Answer: 308cm

Step-by-step explanation: The formula to find the curved surface area of a cylinder is 2πr × h. The formula for curcufrence is 2πr.

So,

2πr (circumfrence)= 44cm.

Height= 7cm.

2πr × h = 44 x 7 = Curved surface area.

Curved surface area= 308cm
