What is the value of X enter your answer in the box
Answer:
x = 27
Step-by-step explanation:
The segment in the triangle bisects ∠ BAC and divides the opposite side into segments that are proportional to the other 2 sides , that is
[tex]\frac{x+8}{2x-5}[/tex] = [tex]\frac{10}{14}[/tex] ( cross- multiply )
10(2x - 5) = 14(x + 8) ← distribute parenthesis on both sides
20x - 50 = 14x + 112 ( subtract 14x from both sides )
6x - 50 = 112 ( add 50 to both sides )
6x = 162 ( divide both sides by 6 )
x = 27

Sometimes you can use the distributive property to expand an expression.
You can expand - 3(5 - x) into the equivalent expression -15 + 3x. Show
you can use the distributive property to expand -4(-a+2) to get an
equivalent expression.
how
Given:
After expanding [tex]-3(5-x)[/tex] we get an equivalent expression [tex]-15+3x[/tex].
The given expression is [tex]-4(-a+2)[/tex].
To find:
The equivalent expression by using distributive property.
Solution:
According to the distributive property of multiplication over addition, if a, b, c are real values, then
[tex]a(b+c)=ab+ac[/tex]
We have,
[tex]-4(-a+2)[/tex]
Using distributive property of multiplication over addition, we get
[tex]-4(-a+2)=(-4)(-a)+(-4)(2)[/tex]
[tex]-4(-a+2)=4a+(-8)[/tex]
[tex]-4(-a+2)=4a-8[/tex]
Therefore, the expression [tex]4a-8[/tex] is equivalence to [tex]-4(-a+2)[/tex].

question: In the given figure ABCD is a parallelogram Find x
Answer:
x=3
Step-by-step explanation:
5x-1=3x+5(opposite sides of a parallelogram is equal)
5x-3x=5+1
2x=6
x=6/2
x=3
therefore the value of x is 3
Answer:
Step-by-step explanation:
So in a parrelelagram, we know that the top and bottom side are equivelent in length.
This is the same with the left and ride side as well.
So knowing this, we can solve x by setting up this equation:
5x-1=3x+5
This works because we know both sides are equvlent, but have different x values and number values.
Lets start solving:
5x-1=3x+5
First lets move all the numbers to one side:
5x=3x+6
Now lers get the variable to one side:
2x=6
Now divide both sides to get x alone"
x=3
This is your answer!
Hope this helps!

Answer:
7) 14✓2
8) 14
are the answers.
Step-by-step explanation:
in a triangle the sum of angles is 180 deg.
the third angle will be = 180 - 90 - 45
= 45 deg
since 2 angles in the triangle are 45 deg it means the triangle is isosceles
and in isosceles triangle the sides opposite to equal angles are equal which means
z = 14 (answer to question 8)
now in right angle triangle, by pythogoras theorem,
hypotenuse ² = base ² + height ²
thus
[tex] {w}^{2} = {z}^{2} + {14}^{2} \\ {w}^{2} = {14}^{2} + {14 }^{2} \\ {w}^{2} = 2 \times {14}^{2} \\ w = \sqrt{2 \times {14}^{2} } \\ = \sqrt{2} \times 14 \\ = 14 \sqrt{2} [/tex]

What is the domain and range of the function?The domain of a function is defined as the set of all the possible input values that are valid for the given function.
The range of a function is defined as the set of all the possible output values that are valid for the given function.
We are given that;
The table
Now,
we can find the range of the function based on the input-output table:
The output values in the table are 100, 105, 110, 115, 120, 125, and 130. These are the possible pay per month that the function can produce for different hours of training.
To write the range as a set, we use curly braces {} and separate the elements by commas. We do not need to repeat any values that appear more than once in the table.
Therefore, by range of the function the answer will be {100, 105, 110, 115, 120, 125, 130}.

Compound interest of $1000 is invested at 10% compounded continuously, the future value s at any time t in years is given by s=1000 e^0.1t how log before the investment doubles?
Answer: 6.93 years
Step-by-step explanation:
Given
Rate of interest is [tex]r=10\%[/tex]
Future value is given by [tex]s=1000e^{0.1t}[/tex]
For the investment to double itself, i.e. [tex]s=2000[/tex]
[tex]\Rightarrow 2000=1000e^{0.1t}\\\Rightarrow 2=e^{0.1t}\\\\\text{Taking log both sides}\\\\\Rightarrow \ln 2=0.1t\\\\\Rightarrow t=\dfrac{\ln 2}{0.1}\\\\\Rightarrow t=6.93\ \text{years}[/tex]
It takes around 6.93 years to double the investment.

Find the measure of the largest angle.
Answer:
4x-7
Step-by-step explanation:
Solve for x:
180 = 44 + 3x - 11 + 4x - 7
Combine like terms: 180 = 26 + 7x
Simplify: 154 = 7x
Simplify: 22 = x
Substitute: 3(22) - 11 = 55 and 4(22) - 7 = 81
Create inequality: 44 < 55 < 81

What is the volume of this rectangular prism?
5 cm
3 cm
4 cm
A. 12 cm3
B. 94 cm3
C. 120 cm3
D. 60 cm3
Answer:
The volume of this rectangular prism is D. 60[tex]cm^{3}[/tex].
Step-by-step explanation:
In order to find the volume of a rectangular prism, we need to multiply the length by the width, and then multiply their product by the height of the prism. We can write what I said above as a formula...
V = l × w × h
(In the formula above "V" is the volume, "l" is the length, "w" is the width, and "h" is the height).
Now we just substitute the values into the formula and we get...
V = l × w × h
V = 4cm × 3cm × 5cm
V = 60[tex]cm^{3}[/tex]
Therefore, the volume of this rectangular prism is D. 60[tex]cm^{3}[/tex].
