Answer:
[tex]BD = 19[/tex]
Step-by-step explanation:
Given
[tex]CD = 2x[/tex]
[tex]BD = 3x + 4[/tex]
[tex]BC = 2x -1[/tex]
Required
Find BD
Since C is on BD, we have:
[tex]BD = BC + CD[/tex]
Substitute values for BD, BC and Cd
[tex]3x + 4 = 2x - 1 + 2x[/tex]
Collect Like Terms
[tex]3x - 2x - 2x = -1 - 4[/tex]
[tex]-x = -5[/tex]
Multiply through by -1
[tex]x = 5[/tex]
Substitute 5 for x in [tex]BD = 3x + 4[/tex]
[tex]BD = 3 * 5 + 4[/tex]
[tex]BD = 19[/tex]
Find the value of x!!!!!!
Answer:
Sum of 3 angles in a triangle=180
x+55+72= 180
x+ 127=180
x= 180-127
x= 53
Answer:
63 degrees
Step-by-step explanation:
All angles of a triangle always add up to 180 degrees.
So you take both angles and add them together-55+72=117
You then would take 180 and subtract the total- 180-117=63
And that would be your final answer
use the distributive property to find the sum of 112+68
Step-by-step explanation:
(56+56)+(34+34)
2(56+34)
2(90)
180

Which statement best describes how Charlemagne expanded his territory in Europe? He led the Catholic Church as the Holy Roman emperor. He became king of the Franks and then conquered other lands. He created schools in the kingdom and then became emperor of Saxony. He created new laws that allowed him to become king of the Lombards and Saxons.
Answer:
He became king of the Franks and then conquered other lands.
Step-by-step explanation:
Charlemagne became king of the Franks after the death of his father, Pepin the Short.
He inherited a sizeable portion of land that included what is now France, the Low Countries, and parts of Germany.
Charlemange launched several military campaigns throughout his long reign (he ruled for 46 years), and was highly successful in most of them. He conquered Northern and Central Italy, what is now Switzerland and Austria, and the majority of modern day Germany.
He was crowned Holy Roman Emperor in the year 800 by Pope Leo III. In exchange for this, Charlemange ceded a section of Central Italy to the Pople: the Papal States, which would be under direct control of the Roman Catholic Church until the Napoleonic Era.

How do u write “the quotient of c and 2 “ as a variable expression?
The variable expression c/2 represents the quotient of c and 2, where c can be any numerical value or variable.
To write "the quotient of c and 2" as a variable expression, we can use the division operation to represent the quotient.
The variable expression would be:
c/2
c represents the variable, and dividing c by 2 gives us the quotient of c and 2.
Let's break it down further to understand this expression in more detail:
The term "quotient" refers to the result of dividing one quantity by another.
We are interested in the quotient of c and 2.
The variable c represents an unknown value or a variable that can take on different numerical values.
The number 2 is the divisor or the quantity by which we divide c to find the quotient.
By using the division operator (/), we can create a variable expression that represents the quotient of c and 2.
We evaluate this expression by substituting specific values for c, we will obtain the result of dividing c by 2.
If we let c = 10, then the expression c/2 would evaluate to 10/2, which equals 5.
If c = 6, the expression c/2 would evaluate to 6/2, which equals 3.

Step-by-step explanation:
Zheng made a mistake as the side AC does not correspond to the side CD. The correct option is C.
What is congruency?The Side-Angle-Side Congruence Theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one is congruent to the included angle and corresponding two sides of the other triangle. An included angle is found between two sides that are under consideration.
In the given figure the triangles △ABC and △CED are similar the incorrect statement made by Zheng is that the side AC does not correspond to the side CD.
It means that the △ABC and △CED will not be similar to each other. But the two triangles △ABC and △CED are similar.
Therefore, Zheng made a mistake as the side AC does not correspond to the side CD. The correct option is C.

Write an equation of the parabola in intercept form that passes through (-2,0.05) with x-intercepts of -7 and -3.
Answer:
y = 0.01(x +7)(x +3)
Step-by-step explanation:
For intercepts p and q, the equation will be ...
y = a(x -p)(x -q)
For the given intercepts, the equation is ...
y = a(x +7)(x +3)
We can find the value of 'a' by using the given point:
0.05 = a(-2+7)(-2+3) = 5a
0.01 = a . . . . divide by 5
The complete equation is ...
y = 0.01(x +7)(x +3)

A guppy was swimming 8 feet below the surface of the river. It swam down 6 more feet
to escape a large, hungry fish. What is the position of the guppy now relative to the
surface?
To solve the problem, Jenna subtracted 8 - 6 and came up with an answer of 2 feet. Is Jenna
correct? Why or why not?
Yes, Jenna is correct.
No. The answer should have been -2 feet, not 2 feet, because the guppy is
below the surface.
No. Jenna should have subtracted -8 - 6 because the guppy started 8 feet
below the surface and swam down 6 more feet.

Use the steps to finish writing an equivalent equation for y in terms of x. −6x = 12 − 4y 1. Subtract 12 from both sides: −6x − 12 = −4y 2. Divide −4 to both sides: −6x − 12 −4 = −4y −4 x + 3 = y
Answer: 1.5x
Step-by-step explanation:
Answer:
1.5x + 3 = y
Step-by-step explanation:
−6x = 12 − 4y
1. Subtract 12 from both sides: −6x − 12 = −4y
2. Divide −4 to both sides: -6x-12 over -4 = -4y over -4
