Answer:

Part a) The length of the rectangle is 12\ ft

Part b) The area of rectangle is 72\ ft^{2}

Step-by-step explanation:

step 1

Find the length

Let

L-----> the length of the rectangle

W---> the width of the rectangle

we know that

The perimeter of rectangle is

P=2(L+W)

P=36\ ft

so

36=2(L+W)

18=(L+W) ----> equation A

L=2W -----> equation B

substitute equation B in equation A

18=(2W+W)

solve for W

18=3W

W=18/3=6\ ft

Find the value of L

L=2(6)=12\ ft

step 2

Find the area

The area of rectangle is equal to

A=LW

substitute the values

A=(12)(6)=72\ ft^{2}

The density of an object can be calculated by dividing the object's mass by its volume. A rectangular prism has a density of 15g
weeeeeb [17]
Well, first you would divide 5625 by 15 to get the volume of the rectangular prism. So 375. Next, you would divide 375 by 3 which is 125 then by 5 do you get___. That would be your answer. So divide 125 by 5 to get your answer.

The function f(x)=2/3x-4 was replaced with f(x+k)=2/3x-6 what is the value of k
HACTEHA [7]

Answer:

The given function f(x)=\frac{2x}{3}-4 was replaced with f(x+k)=\frac{2x}{3}-6 then the value of k is -3

that is k=-3.

Step-by-step explanation:

The given function is f(x)=\frac{2x}{3}-4\hfill (1)

and when x=x+k then f(x+k)=\frac{2x}{3}-6\hfill (2)

Now to find the value of k:

Put x=x+k in the function f(x)

f(x)=\frac{2x}{3}-4

f(x+k)=\frac{2(x+k)}{3}-4

f(x+k)=\frac{2x+2k}{3}-4\hfill (3)

Now comparing equations (2) and (3) we get

f(x+k)=\frac{2x+2k}{3}-4=\frac{2x}{3}-6

\frac{2x+2k}{3}-4=\frac{2x}{3}-6

\frac{2x+2k}{3}-4-\frac{2x}{3}+6=0

\frac{2x}{3}+\frac{2k}{3}-4-\frac{2x}{3}+6=0

\frac{2k}{3}+2=0

\frac{2k}{3}=-2

k=\frac{-2\times 3}{2}

k=-3

Therefore k=-3

Therefore the given function f(x)=\frac{2x}{3}-4 was replaced with  f(x+k)=\frac{2x}{3}-6 then the value of k is -3

that is k=-3.
