Expression representing the length 'x' will be, [tex]x=\frac{(AB)(AC)}{AC+BC+AB}[/tex].
In-center of a triangle,In-center of a triangle defines the center of a circle inscribed in the triangles (touching all sides),Perpendicular drawn from in-center to the sides of the are equal in measures (radii of the inscribed circle).Use the hint → Area of the large triangle = sum of the small triangles inside the larger triangle
Area of ΔABC = [tex]\frac{1}{2}(AB)(AC)[/tex]
Area of ΔADC = [tex]\frac{1}{2}(AC)(x)[/tex]
Area of ΔBDC = [tex]\frac{1}{2}(BC)(x)[/tex]
Area of ΔADB = [tex]\frac{1}{2}(AB)(x)[/tex]
Since, Area of ΔABC = Area of ΔADC + Area of ΔBDC + Area of ΔADB
[tex]\frac{1}{2}(AB)(AC)=\frac{1}{2}(AC)(x)+\frac{1}{2}(BC)(x)+\frac{1}{2}(AB)(x)[/tex]
[tex](AB)(AC)=[(AC)+(BC)+(AB)](x)[/tex]
[tex]x=\frac{(AB)(AC)}{AC+BC+AB}[/tex]
Therefore, expression representing the length 'x' will be [tex]x=\frac{(AB)(AC)}{AC+BC+AB}[/tex].

would this angle be name angle CUE or CUT ?
Answer:
[tex]\huge\boxed{\angle\text{CUE}}[/tex]
Step-by-step explanation:
We can model what both readings of this angle would be. Angle names are usually formed by taking the two lines that form to intersect this angle at a vertice, and these 3 make up the name.
Angle ∠CUT would be formed by the lines CU and UT. We can see that this is not the case, as the angle is formed by lines CU and CE.
Since they intersect at point U, that means the angle name would be CUE.

Which of the following is true about the order of operations?
1. Multiplication comes before division.
2. Addition and subtraction are done from left to right.
3. Addition and subtraction are done before multiplication and division.
4. Exponents are the first operation to be completed.
Answer:
2
Step-by-step explanation:
Multiplication comes before division. To add or subtract we can do from left to right by thousand, hundred, or any respective place value thus options (1) and (2) are correct.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
Subtraction = Minus of any two or more numbers with each other called subtraction.
Using the PEMDAS rule,
Parenthesis = 1st
Exponents = 2nd
Multiplication = 3rd
Divide = 4th
Addition = 5th
Subtraction = 6th
Suppose an addition,
120 + 320
Now add from left to right,
100 + 300 = 400
20 + 20 = 40
Now, 400 + 40 = 440
Thus, adding from left to right is true.
Hence "Multiplication comes before division. To add or subtract we can do from left to right by thousand, hundred, or any respective place value ".

The base of a traingular field is twice its altitude , If the cost of levelling the field , at the rate of rupess 10 per m2 is rupees 4,000 , find it base and altitude
Answer:
Base=40m and
Altitudes=20m
Step-by-step explanation:
Area of the field can be calculated as
Area= total cost / rate
Where total cost= 4,000 rupees
Rate= 10 per m2
Area of the field= 4000/10
= 400m^2
Let the altitudes be denoted as "x metre"
Then the base = 2x
Area= 1/2bh
Where b= base
h= altitudes
Then if we substitute we have
400m^2= 1/2× x × 2x
400= x^2
x= √400
x=20m
Then altitudes = 20m
the base = 2x= 2×20=40m
Hence, it base and altitude are 40m and 20m respectively.
A bag of dog food says that it now contains 20% more. Originally, it came with 63 ounces of dog food. How much dog food does the bag come with now? Set up the double number line to show that 63 ounces is 100%.
Answer:
75.6 ounces
Step-by-step explanation:
Step one.
Given data
we are told that the original quantity of food is 63 ounces
and the increase is in food is by 20%
Step two:
let us find the increase in ounces
=20/100*63
=0.2*63
=12.6 ounces
Hence the amount of food in the bag now is
=12.6+63
=75.6 ounces

You are kayaking at a pace of 63 feet every 12 seconds. Your friend's pace is 21 feet every 2 seconds. Are you and your friend kayaking at the same pace? If not, who is faster?
Answer:
Your friend is kayaking faster.
Step-by-step explanation:
The way to approach this answer is by putting one of them in terms of the other. So that both are in terms of the same time. If you kayak 63 feet in 12 seconds how many feet do you kayak in 2 seconds? Simply divide by 6. 63/6 = 12/6. So, in 2 seconds (12/2) you kayak 10.5 feet (63/6). But your friend kayaks 21 feet in the same time... so he's going faster.

Solve for x:
2x + y = -2
4x + y = -8
Answer:
x = -3
Step-by-step explanation:
2x + y = -2
4x + y = -8
2x + y = - 2
y = -2x - 2
4x + y = - 8
y = -4x - 8
y = -2x - 2
y = -4x - 8
-2x - 2 = -4x - 8
4x - 2x = 2 - 8
2x = -6
2x/2 = -6/2
x = -3

Use the figure to find the measures of the numbered angles. ∠5 = ∠6 =
Answer:
∠ 5 = 49°, ∠ 6 = 131°
Step-by-step explanation:
∠ 5 and 49° are corresponding angles and are congruent, then
∠ 5 = 49°
∠ 5 and ∠ 6 are adjacent angles and are supplementary, sum to 180° , that is
∠ 6 + ∠ 5 = 180°
∠ 6 + 49° = 180° ( subtract 49° from both sides )
∠ 6 = 131°

since the hypotenuse of 6 cm is shorter than the base of 8 cm there is something wrong with this drawing. The box can't be square so maybe answer C is good but.. since this box isn't a right angled box.. we really don't know. This is a bad question b/c it's making the appearance of being a right angle but it can not be. Like an Escher drawing.. not possible irl
The volume of the rectangular prism is 8×2×3 cubic in or 48 cubics in option (B) 8×2×3 cubic in is correct.
What is a rectangular prism?It is defined as the six-faced shape, a type of hexahedron in geometry.
It is a three-dimensional shape. It is also called a cuboid.
The missing height of the rectangular prism is 3 cm
It is given that:
The rectangular prism is shown in the picture with dimensions.
As we know, the volume of the rectangular prism is given by:
V = length×width×height
Length = 2 cm
Width = 8 cm
Height = 3 cm
The volume of this figure:
V = 2×8×3
Or
The volume of this figure V = 8×2×3 cubic in
Thus, the volume of the rectangular prism or the volume of the figure is 8×2×3 cubic in or 48 cubics in option (B) 8×2×3 cubic in is correct.

Step-by-step explanation:
Answer:
(2,1)
Step-by-step explanation:
2x - 2y = 2
5x + 2y = 12
2x + 5x = 7x
-2y + 2y = 0
2 + 12 = 14
7x = 14
7x/7 = 14/7
x = 2
2x - 2y = 2
2(2) - 2y = 2
4 - 2y = 2
-2y = 2 - 4
-2y = -2
-2y/-2 = -2/-2
y = 1
