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
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.

Make r the subject of the formula t=r/r-3
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
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.

find the domain of the graphed function -4-4 x is all real numbers
Domain and range:
The domain of a function is all the values the the input assumes.
The range of a function is given by all the values that the output assumes.
In a graphic:
The domain is given by the x-values, the horizontal axis.
The range is given by the y-values, the vertical axis.
In this question:
x, in the horizontal axis, assumes values between -4 and 2.
The closed circle at x = -4 and x = 2 indicates that these values are part of the interval.
Thus, the domain of the graphed function is: [tex]-4 \leq x \leq 2[/tex], and the correct answer is given by option D.
For more about domain and range of functions, you can check: https://brainly.com/question/21853810?referrer=searchResults
D. [tex]-4 \le x \le 2[/tex]
The procedure of solution consist consist in determine graphically the Domain of the Function shown in the figure. In this case, the Domain is the Set of values of [tex]x[/tex] in Interval notation, which represented in the "horizontal" axis of the Cartesian Plane. Please notice that black points means that given Function includes extreme values.
By visual examination of the function, we conclude that domain of the function is represented by:
[tex]Dom\{f(x)\} = [-4, 2][/tex]
Which is equivalent to the following expression in Inequality notation:
[tex]-4 \le x \le 2[/tex]
Therefore, we conclude that right answer is D.

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.
