Perimeter:

$6y + 12$

Area:

${2y}^{2} + 12y$

Step-by-step explanation:

Perimeter of a rectangle : P= 2( L + w)

in this case it would be 2(y+6) + 2(2y)

= 2y+12 + 4y

simplified to 6y +12

Area of a rectangle : A= LW

=(y+6)(2y)

We foil and get

${2y}^{2} + 12y$

Let f(x)=4x+9. Write a function g whose graph is a reflection in the y-axis of the graph of f. g(x)= ?

frez [133]

Answer:

$g(x)=-4x+9$

Step-by-step explanation:

So we know that:

$f(x)=4x+9$

To reflect across the <em>y-axis</em>, instead of x, use -x. Therefore:

$g(x)=f(-x)=4(-x)+9$

Simplify:

$g(x)=-4x+9$

And that's our answer :)

The equation of the circle whose center is at (3, 7) and whose radius is 6 is a. (x + 3)² + (y + 7)² = 6 b. (x + 3)² + (y + 7)²

kicyunya [14]

$\bf \textit{equation of a circle}\\\\ 
(x- h)^2+(y- k)^2= r^2
\qquad 
center~~(\stackrel{3}{ h},\stackrel{7}{ k})\qquad \qquad 
radius=\stackrel{6}{ r}
\\\\\\
(x-3)^2+(y-7)^2=6^2\implies (x-3)^2+(y-7)^2=36$

There are 24 cans of soda arranged in 4 rows of 6 cans each. Each can is a

Studentka2010 [4]

Answer:

23,040 cm^3.

Step-by-step explanation:

The case will be 6 * diameter of a can in length,

= 6* 8= 48 cm.

The width will be 4 * 8 = 32 cm.

The height = height of each can

= 15 cm.

So the volume of the case = 15*32*48

= 23,040 cm^3.
