Answer: m=6

Step-by-step explanation:

9+12m=6+15\left(m-1\right)

6+15\left(m-1\right)=15m-9

9+12m=15m-9

subtract 9 on both sides

9+12m-9=15m-9-9

12m=15m-18

subtract 15m on both sides

12m-15m=15m-18-15m

-3m=-18

divide by -3 on both sides

\frac{-3m}{-3}=\frac{-18}{-3}

since \frac{-a}{-b}=\frac{a}{b}

\frac{-18}{-3}=6

m=6

If the radius of the circle is multiplied by a factor of 3, then the area of the circle is multiplied by a factor of
Oksi-84 [34.3K]
\bf \textit{area of a circle}\\\\
A=\pi r^2\quad 
\begin{cases}
r=radius\\
-----\\
r=\stackrel{r\times 3}{3r}
\end{cases}\implies A=\pi (3r)^2
\\\\\\
A=\pi (3^2r^2)\implies A=9(\pi r^2)

notice, if the original area was πr², then the new area has a factor in front of it, that much.

Please help me with this, image attached.
Ainat [17]

Answer: x = 9 (choice D)

Assuming this is a geometric kite, then this means that triangle ABD is a reflection over the line BD to get triangle BCD. Furthermore, this points to AB and BC being the same length

AB = BC

3x - 5 = 22 .... substitution

3x - 5+5 = 22+5 .... add 5 to both sides

3x = 27

3x/3 = 27/3 ..... divide both sides by 3

x = 9
