$C\text{ = 9}\pi\text{ in}$

To find the circumference, we will have to multiply the length of the diameter by pi

Mathematically, we have this as;

$\begin{gathered} C\text{ = }\pi\times d \\ C=\text{ }\pi\times9\text{ = 9}\pi \end{gathered}$

Answer:

Roots are x=6 and - 4

Step-by-step explanation:

2(x-6)(x+4)=0

(x-6)=0 or (x+4)=0

x=6 or x=-4, their multiplicities is 1

One day, a person went to a horse racing area. Instead of counting the number of humans an horses, he conuted 74 heads and 196 l

BigorU [14]

X = the number of humans and y = the number of horses.

x+y=74
2x+4y=196

Because the number of humans and horses together is 74, and the total number of legs (2 per every human, x, and 4 per every horse, y) is 196. Then, just use elimination to solve.

$-2(x+y=74)\\2x+4y=196\\\\-2x-2y=-148\\2x+4y=196\\\\2y=48\\y=24$

So, now that you have y, you can plug it into the first equation to find x:

$x+y=74\\x+24=74\\x=50$

So, x = 50 and y = 24, so there are 50 humans and 24 horses.
The correct answer is B.
