To prove that ΔDEF ≅ ΔDGF by SSS, what additional information is needed?
1. ∠DEF ≅ ∠DGF
2. ∠DFE ≅ ∠DFG
3. DE ≅ DG
4. DG ≅ GF
The additional information needed to prove that ΔDEF ≅ ΔDGF by the SSS Congruence Theorem is: 3. DE ≅ DG
Recall:
If two triangles have three pairs of congruent sides, the two triangles can be proven to be congruent triangles based on the SSS Congruence Theorem.In the figure given, ΔDEF and ΔDGF is shown to have the following two pairs of congruent sides:
EF ≅ GF
DF ≅ DF (both triangles share a common side)
We need an additional information that shows that the third sides of both triangles (DE and DG) are congruent to each other.
Therefore, the additional information needed to prove that ΔDEF ≅ ΔDGF by the SSS Congruence Theorem is: 3. DE ≅ DG

Solve the system of equations. If the system has no solution, say that it is inconsistent. Graph the lines of the system.
x + y = 7
x - y = 5
Select the correct choice below and, if necessary, fill in any answer boxes within your choice.
A. The solution is x= 6 and y = 1. (Type integers or simplified fractions.)
** i know that x=6 and Y=1. I don’t know how to graph it. It gives me a hint that the lines need to be in slope intercept form but again, I dont know how to graph! **
So the easiest way would be to change them into slope intercept form
x + y = 7
y = - x + 7
x - y = 5
y = x - 5
The coefficient of x is the slope, since none of them have a coefficient, their slopes are 1. The first line has negative x which means the slope is negative one, which you can draw from top left to bottom right and a positive slope is drawn from top right to bottom left.
The number after x is the y-intercept which is where the line intercepts the y-axis.
To draw, put a dot on the y-intercept and with a slope of one, go up and right one, or the opposite which is go down one and left one and put another dot and draw a line between the two dots. With a slope of negative one, go up one and go left one, or the opposite which is go down one and right one and draw a line between the two dots.
anyone can u please help me.

Step-by-step explanation:
52 square inch is the surface area of the given card box.
What is the Surface area?The area or region that an object’s surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has. There are numerous shapes and dimensions in geometry, including spheres, cubes, cuboids, cones, cylinders, etc. Each form has its own volume and surface area.
Given a card box of size 8 by 10 inches. the surface area of the card box can be calculated by dividing the card box into three parts, such that:
one piece with a dimension of 4 by 10 and another piece with a dimension of 2 by 3 inches.
Area of card of 4 by 10-inch dimension = 4*10 = 40
Area of card of 2 by 3 dimension = 2 *3 = 6
Thus,
The total area of the card box = Area of bigger card +2*area of smaller card
The total area of the card box = 40 + 2*6 = 52 inches square

Xavier is going to use a computer at an internet cafe. The cafe charges an initial fee to use the computer and then an additional price per minute of usage. Let C represent the total cost of using a computer for t minutes at the internet cafe. A graph of C is shown below. Write an equation for C then state the slope of the graph and determine its interpretation in the context of the problem.
C = ???
The slope of the function is ? which represents:
A: The total charge of using a computer
B: The number of minutes the computer was used
C: The additional charge per minute
D: The initial charge to use a computer
Answer:
C = 1/5t +6
slope: 1/5, (C) The additional charge per minute
Step-by-step explanation:
Before we can write the function, we need to know the slope of the line. Marked points are separated by 5 units horizontally (run=5) and 1 unit vertically (rise=1). The slope is ...
m = rise/run = 1/5
The initial charge is the C-intercept: 6. The function can be written in slope-intercept form as ...
C = 1/5t +6
__
As we saw above, the slope of the function is 1/5, which represents ...
the additional charge per minute

Answer:
The length of the diagonal is 8.3
Step-by-step explanation:
The formula for finding the length of the diagonal in rectangular prism is:
d = √[tex](l^{2} + w^{2} + h^{2})[/tex]
"l" represents the length which is 7
"w" represents the width which is 4
"h" represents the width which is 2
Substitute the values to the formula.
d = √([tex]7^{2} ) + (4^{2} ) + (2^{2} )[/tex]
d = √49 + 16 + 4
d = √65 + 4
d = √69
Find the square root of 69 using calculator.
d = 8.30662386292
The direction said round the answer to the nearest tenth. So the answer must be 8.3

A garden has width √6 and length 3√6. What is the perimeter of the garden in simplest radical form?
Answer:
[tex]8\sqrt{6}[/tex] units
Step-by-step explanation:
Assuming the garden is in a rectangular shape:
The perimeter of a shape is the sum of all the sides, so in the case of a rectangle, this is
P=l+l+w+w=2(l)+2(w)=2(l+w)
where l is the length and w is the width. Here, you are given the length and width, so plug them in.
[tex]P=2(l+w)=2(3\sqrt{6}+\sqrt{6})=2(4\sqrt{6})=8\sqrt{6}[/tex]
Your answer is [tex]8\sqrt{6}[/tex] units.

Solve for x. x/5 = 20
Answer:
100
Step-by-step explanation:
x / 5 = 20
Cross multiply,
x = 20 * 5
x = 100
Answer:
X = 100
Step-by-step explanation:
x/5 = 20
You do the same thing on the top as the bottom to cancel out and leave x by itself
5x/5 =20
whatever you do for one side you do for the other side
5x/5 = 20*5
the 5 cancel out leaving x by itself
so x = then 20 times 5 = 100
so x =100
