10x + 8 = 21
x = 1.3
Step-by-step explanation:
a)
In pentagon ABCDE,
AB = DE = 2x + 3 and BC = CD = x + 1
Perimeter of pentagon ABCDE = 21
4x + 2(2x + 3) + 2(x + 1) = 21
4x + 4x + 6 + 2x + 2 = 21
[tex] \purple {\boxed {\bold{10x + 8 = 21}}} [/tex]
b)
10x = 21 - 8
10x = 13
[tex]x = \frac{13}{10} \\ x = 1.3 \: cm [/tex]

x = 17°, m∠ A = 114°
Step-by-step explanation:
We can tell that these pair of angles are corresponding, provided;
Line 1 ║ Line 2, AB ∩ Line 1 and Line 2 ⇒ corresponding ∠s ≅,
m∠ A = m∠ B ⇒ Substitute values of A and B,
6x + 12 = 3x + 63 ⇒ Subtract 3x on either side,
3x + 12 = 63 ⇒ Subtract 12 on either side of equation,
3x = 51 ⇒ Divide either side by 3,
x = 17 ⇒ Substitute value of x to solve for m∠ A,
m∠ A = 6 * ( 17 ) + 12,
m∠ A = 102 + 12,
m∠ A = 114
Solution; x = 17°, m∠ A = 114°
Answer:
x = 17, ∠A = 114°
Step-by-step explanation:
I'm 8 years old and I know how to do this.
6x + 12 = 3x + 63
3x + 12 = 63
3x = 51
x = 17
6(17) + 12
102 + 12 = 114
Water is draining from an aquarium at a rate of
3 gallons per minute. Write a multiplication expression using integers to show the total change to the amount of water in the aquarium after 45 minutes of draining. Then determine and explain that amount.
Answers
135 gallons of water in the aquarium after 45 minutes of draining.
What are Arithmetic operations?Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
Given that water is draining from an aquarium at a rate of 3 gallons per minute.
The total change in the amount of water in the aquarium after 45 minutes of draining is as:
⇒ 45×3
Apply the multiplication operation in the integers,
⇒ 135 gallons
Hence, 135 gallons of water in the aquarium after 45 minutes of draining.

Find the volume of the cylinder in terms of pi.
Answers
Answer:
The volume of the cylinder would be 226.19in however if you need it in terms of pi it would be V = 72 π in3
Step-by-step explanation:
V=πr2h=π·62·2≈226.19467, hope I was able to help you
And that is basically what you have to do
Answer:
72π inches^3
Step-by-step explanation:
The volume of a cylinder can be found using:
v=πr^2h
We know that the radius is 6 inches, and the height is 2 inches. So, we can substitute 6 in for r, and 2 in for h.
v= π 6^2 *2
Evaluate the exponent
v= π 36*2
Multiply 36 and 2
v= π72
So, the volume in terms of pi is:
72π inches^3
Solve for K: 40 + K = 56
K=
Answers
Answer:
k=16
Step-by-step explanation:
To solve this, we can isolate k.
40+k=56.
We can do this by subracting 40 from both sides.
40+k-40=k
56-40=16
k=16
First isolate or get k by itself by subtracting 40 from both sides.
That leaves us with k = 16.
To check our answer, substitute 16 back into the equation.
So we have 40 + (16) = 56 or 56 = 56.

There are 3 Answers:
Choice A) reflect the dilated circle over the horizontal line through point C.
Choice D) rotate the dilated circle 180 degrees around point C
Choice E) translate the dilated circle to center B
Due to symmetry, rotations and reflections do not change a circle. This is why we are able to rotate around point C so that it looks like a translation has occurred. A similar thing happens with reflections as well.
The correct Answers:
A) reflect the dilated circle over the horizontal line through point C.
D) rotate the dilated circle 180 degrees around point C
E) translate the dilated circle to center B
What is transformation?A transformation is a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system.
Given is circle A is dilated so that it is the same size as circle B, we need to determine the transformations performed to show that the circles are similar.
We know that,

The area of a parallelogram = Base x Height
We are given that top of the table measures 18 inches by 14 inches. If each tile has four sides of length 3 inches with a height of 2 inches.
Area of table = Base x Height
= 18 x 14
= 252
Area of glass parallelogram tiles = Length x width
= 3 x 2
= 6
Now,
252 = 6 x number of tiles

Which function can be used to model the graphed geometric sequence?
f(x + 1) = Five-sixthsf(x)
f(x + 1) = Six-fifthsf(x)
f(x + 1) = Five-sixths Superscript f (x)
f(x + 1) = Six-Fifths Superscript f (x)
Answers
Answer:
f(x+1)=(5/6)f(x)on: Five-sixths Superscript f (x)
EXPLANATION:
The defining characteristic of a geometric sequence is that each term is a constant multiple of the previous term, called the common ratio denoted r in the rules for geometric equations.
625/750=750/900=etc=r=5/6
The function that can be used to model the graphed geometric sequence is f(x + 1) = 5/6 f(x).
What is the general equation of a Straight line? What is a Geometric sequence?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
A geometric sequence is a sequence such that -
a(n + 1)/a(n) = K {constant}
[K] is called common ratio.
Given is a graph representing a geometric sequence.
Now, for -
f(2) = 1080
and
f(1) = 1296
So -
f(2)/f(1) = 1080/1296 = 5/6
In general -
f(x + 1)/f(x) = 5/6
f(x + 1) = 5/6 f(x)
Therefore, the function that can be used to model the graphed geometric sequence is f(x + 1) = 5/6 f(x).

Height: 8 inches
Havana is wrapping a gift whose box's dimensions are all twice the length of the lengths in Jake's box. How many times larger is the surface area of Havana's box than Jake's box?
Answers
Answer:
Because you are looking for square inches of wrapping paper, you are looking for the surface area of the box. A three-dimensional box has a top and bottom that are the same size, a front and back that are the same size, and 2 sides that are the same size...or SA = 2(top/bottom area) + 2(front/back area) + 2(side/side area). Our equation fills in nicely like this:
SA = 2(6 * 14) + 2(6 * 8) + 2(14 * 8)
SA = 2(84) + 2(48) + 2(112)
SA = 168 + 96 + 224
SA = 488 square inches of paper to wrap the box.
