Perimeter of a rectangle is double of sum of its length and width. The perimeter P of the considered rectangle is: Option B: [tex]P = 2x + 2y - 8[/tex]
What is perimeter?Its the sum of length of the sides used to made the given figure.
For a rectangle, as its two sides are equal to its length and two other sides are equal to its width, thus, its perimeter is:
[tex]P = 2 \times length + 2 \times width = 2(length + width)[/tex]
For the given case, it is already given that:
The length of the considered rectangle = x + 5 units
The width of the considered rectangle = y - 1 units.
Thus, we get this rectangle's perimeter as:
[tex]P = 2( x + 5 + y - 1) = 2(x + y + 4) = 2x + 2y - 8\\\\P = 2x + 2y - 8 \: \rm units[/tex]
Thus, The perimeter P of the considered rectangle is: Option B: [tex]P = 2x + 2y - 8[/tex]

Consider the following figure where △ABC ~ △DBE.
Triangle A B C contains two points and a horizontal line segment.
The left side of the triangle starts at vertex A, travels up and to the right, and ends at vertex B.
The right side of the triangle starts at vertex B, travels down and to the right, and ends at vertex C.
The bottom side of the triangle is horizontal, starts at vertex A on the left, and ends at vertex C on the right.
Point D is located on side A B but is closer to A than B.
Point E is located on side B C but is closer to C than B.
The horizontal line segment extends from point D and ends at point E.
Given:
CB = 12, CE = 2, AD = 5
Find:
DB
(Hint: Let DB = x, and solve an equation).
DB =
Given that △ABC and △DBE are similar triangles, the length of DB is: 25
What are Similar triangles?The ratio if the corresponding sides of two triangles that are similar are the same, meaning, their sides are proportional.
Given that:
△ABC ~ △DBECB = 12CE = 2AD = 5Thus:
Let DB = x
Therefore:
BD/BA = BE/CB
Substitute
x/(x + 5) = 10/12
Cross multiply
12x = 10x + 50
12x - 10x = 50
2x = 50
x = 25
Therefore, given that △ABC and △DBE are similar triangles, the length of DB is: 25

Answer:
It can't be anything other that a maybe the question is wrong ask a tutor
have a nice day
Step-by-step explanation:
Answer:
√a² = |a|
Step-by-step explanation:
√a² = |a| not a
because the amount of "a" can be negative and when it reaches power 2 the minuse sign converts to plus sign , so we must use absolute value : |a| . notice that the answer never can be negative.
example:
a = -2
√(-2)² = √+4 = |-2| = 2 -2

O $27.60
O $26.40
O $13.20
O $6.60
Answer:
Jasmine earned $27.60
Step-by-step explanation:
3x2 = 6$
(Cleaning gutters)
3.60 x 6 = 21.6
(mowing the lawn)
21.6 + 6 = 27.6 = 27.60
Tell whether the angles are adjacent or vertical. Then find x
The Angles are adjacent and since they are both on a straight line it means that the sum of the angle is 180 degrees, so we get the equations:
[tex](6x) + (x - 2)=180\\7x = 182\\x=26[/tex]
So x = 26.

Tony started to run on a treadmill after setting it’s timer for 78 minutes the display says he finished 78% of his run how many minutes have gone by round your answer to the nearest tenth
Answer:
60.9
Step-by-step explanation:
When finding the amount of a percentage you move the decimal to the left twice in the percentage.
So, 78 x .78 = 60.84
Since it needs to be rounded to the nearest tenth, the answer would be 60.9 minutes.

someone please answer this, ill give you brainliest and your getting 100 points.
Answer:
Step-by-step explanation:
First sequence : 10,9.5,9,8.5,...
Let's see the difference between 2 numbers :
10 - 9.5 = 0.5
9.5 - 9 = 0.5
9 - 8.5 - 0.5
So on and so on. So, the common difference between these numbers are 0.5
Next sequence : 200,100,50,25, ...
We see, to get from one number to another, we divide it by 2 / multiply it by 1/2.
200 x 1/2 = 100
100 x 1/2 = 50
50 x 1/2 = 25
So on and so on. So, the common ratio of these numbers are 1/2.
Answer:
Step-by-step explanation:
A common difference is the number you need to get from a chosen number on your left to get to the next number going right.
In the first sequence, you start with 10 on your left.
To get to the next number going right, you need to subtract 0.5 or add - 0.5
In any event, the common difference is -0,5
The second problem is a little harder. It does not follow the same sort of pattern that the first question does. This time you are multiplying or dividing.
200 * 1/2 = 100
100 * 1/2 = 50
50 * 1/2 = 25
25 * 1/2 = 13.5
So the common ratio is 1/2

8:4 and 16:64 are equal ratios?
Hello.
In order to see if the ratios are equal, we have to simplify both of them.
The first ratio is 8:4.
Divide 8 and 4 by 4:
2:1
Now, simplify the second ratio:
16:64
4:16
1:4
Are 2:1 and 1:4 equal? No.
Therefore, 8:4 and 16:64 are not equal ratios.
I hope this helps.

Answer:
Volume of round cake pan = volume of cylinder
Volume of a cylinder = [tex]\pi r^2h[/tex] (where r is the radius and h is the height)
Radius = [tex]\dfrac12[/tex] diameter ⇒ [tex]r=\dfrac72=3.5[/tex]
⇒ volume of round cake pan = [tex]\pi \times 3.5^2 \times 2=24.5\pi[/tex]
= 76.97 in³ (nearest hundredth)
Volume of rectangular cake pan = volume of rectangular prism
volume of rectangular prism = [tex]wlh[/tex] (where w is the width, l is the length and h is the height)
⇒ volume of rectangular cake pan = 6 x 9 x 2 = 108 in³
As 108 > 76.97, the rectangular cake pan has a larger volume
