A vegetable garden is in the shape of a parallelogram with the dimensions shown.Parallelogram A B C D is shown. The length of A B is (4 r minus 2) feet, the length of B C is (2 r + 12) feet, and the length of A D is (3 r + 8) feet.

How many feet of fencing are needed to enclose the garden?

54 feet
68 feet
108 feet
140 feet

Answers

Answer:

t needs 68 feet to enclose the garden.

Step-by-step explanation:

In this problem, we are to solve the sides of a parallelogram ABCD to know the measurement to enclose a garden.

Take note that a parallelogram has two equal lengths and two equal widths. Let us assume that the parallelogram AB = CD is the length and AD = BC is the width.

Solving the problem

First, let us solve for r using the condition AD = BC

AD = BC

3r + 8 = 2r + 12

Simplify the equation

3r - 2r = 12 - 8

r = 4

Next, let us substitute the value of r to AB, BC, CD, and AD.

For AB:

AB = 4r - 2

AB = 4(4) - 2

AB = 16 - 2 = 14

For BC:

BC = 2r + 12

BC = 2(4) + 12

BC = 8 + 12 = 20

For AD:

AD = 3r + 8

AD = 3(4) + 8

AD = 12 + 8 = 20

For CD:

But AB = CD Therefore, CD = 14

Finally, let us solve the perimeter of the parallelogram

Perimeter = AB + BC + CD + AD

Perimeter = 14 + 20 + 20 + 14

Perimeter = 68 feet

Therefore, the fencing needed to enclose the garden is 68 feet.

Answers

Answer:

[tex]r = \frac{3t}{t-1}[/tex]

Step-by-step explanation:

[tex]t = \frac{r}{r - 3}[/tex]

Cross multiply,

t(r - 3) = r

tr - 3t = r

     tr  = r + 3t

 tr - r = 3t

 r(t -1) = 3t

 [tex]r = \frac{3t}{t-1}[/tex]

Answer:

r = 3t/(t - 1)

Step-by-step explanation:

t = r/(r - 3)

t(r - 3) = r

tr - 3t = r

tr = r + 3t

tr - r = 3t

r(t - 1) = 3t

r = 3t/(t - 1)

Is f(x)=6x a direct variation

Answers

Answer:

[tex]f(x)=6x[/tex] is a direct variation.

Step-by-step explanation:

Given the function

[tex]f(x)=6x[/tex]

We have to determine whether the equation [tex]y=6x[/tex] is a direct variation or not.

As we know that in direction variation, y and x increase or decrease by the same factor by the formula

[tex]y=kx[/tex]

where 'k' is the constant of variation

Given the function

[tex]y=6x[/tex]

Here 6 is the constant of variation            ∵ [tex]y=kx[/tex]

Also y and x increase and decrease by the same factor

For example,

when x=6, y = 6(x)=6(6)=36

when x=8, y = 6(x) = 6(8) = 48

Hence, when x increase, the y increases by the same factor.

Therefore, [tex]f(x)=6x[/tex] is a direct variation.

(3m+13)+(4m+21) simplified

Answers

Answer:

(7m+34)

Step-by-step explanation:

Add like terms 3m+4m=7m, 13+21=34

You have to make sure to add like terms.  In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power.

The answer 3m x 4m = 12m^2 3m x 21 = 63m. 13 x 4m = 52m 13 x 21 = 273 so simplify them which equals 12m^2+115m+273
