The perimeter of the figure is given. Find the length of the indicated side.?4x - 4Perimeter = 16x + 6The length of the indicated side is
Answers
Width = 4x + 7
Explanation:The perimeter of the rectangle shown = 16x + 6
The width of the rectangle = 4x - 4
Perimeter of a rectangle = 2(Length + Width )
16x + 6 = 2[ (4x - 4) x Width]
(16x + 6)/2 = (4x - 4) x width
8x + 3 = (4x - 4) x width
Width = 8x + 3 - (4x - 4)
Width = 8x - 4x + 3 + 4
Width = 4x + 7

The TV would not fit as the TV is too tall option (C) is correct after applying the concept of the ratio.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
The aspect ratio is:
= 4:3
Multiply by 16 to the above ratio:
= 64: 48
The height in the area = 47"
But from the aspect ratio the height of the TV = 48"
Thus, the TV would not fit as the TV is a too tall option (C) is correct after applying the concept of the ratio.

do these pairs of values (x and y) represent two quantities that are proportional? x. y3. 125. 206. 249. 36
Answers
Info given
We have the following info given
x. y
3. 12
5. 20
6. 24
9. 36
Solution
In order to see if the two quantites are prportional we can check the following:
k=y/x
If we analyze the first pair of values we have:
k= 12/3=4
And for the next pairs we have:
k= 20/5=4
k= 24/6=4
k=36/9=4
So then as we can see the value of k is the same so then we can say that x and y are proportional since for each unit that x increase y increase 4 units

Eleni's landscaping company placed two orders. The first order was for 13 bushes and 4 trees and totaled $487. The second order was for 6 bushes and 2 trees and totaled $232. What is the price of one tree?
Answers
The required cost of the bushes is $23 and the cost of the tree is $45.
What is arithmetic?
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
Let the prices of bushes are x and prices of tress are y,
According to the question,
13x + 4y = 487 - - - - - -(1)
6x +2y = 232 - - - - - - -(2)
From equation 2
y = 116 - 3x - - - - -(3)
Put this y in equation 1
13x + 4(116 - 3x) = 487
13x + 464 - 12x = 487
x = 487 - 464
x = 23
Now put this x in equation 3
y = 116 - 3(23)
y = 116 - 69
y = 45
Thus, the required cost of the bushes is $23 and the cost of the tree is $45.

a box has the dimensions of 5, 2x, and 6x. Find a total area of all faces of this box
Answers
The total area of the box is 10
Total area
Total area means the area including the base(s) and the curved part. It is the total area covered by the surface of the object.
Given,
A box has the dimensions of 5, 2x, and 6x.
Here we need to find the total area of all faces of this box.
Basically, area is the total area occupied by the surface.
To find the total area of the box, we have to add the all the side values.
So, when we add the side value, then we get,
=> Total area = 5 + 2x + 6x
=> 8x + 5
=> 8x = 5
=> x = 5/8
Here we removed the negative sign because the area doesn't take the negative value.
So, the side values are
=> 2x = 2 (5/8) = 5/4
=> 6x = 6(5/8) = 15/4
Now, we have to find the total area as,
=> 5 + 5/4 + 15/4
=> 5 + 20/4
=> 5 + 5
=> 10
Therefore, the total area of the box is 10.
