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!
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].

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
Hope this help!!!

8.
Find the value for z?
450
A. 7
Z
B. 1412
D. 73
C.
14
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]
answer to question 7
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].
Plzzzz help asap thank you
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

Which relation is a function?
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.

Step-by-step explanation:
The graph of the function f(x)= x²-3 is translated. The new function rule is f(x)= x²-1.
Which statement is true?
a. Every point on the graph is shifted down 1 unit.
b. Every point on the graph is shifted left 1 unit.
c. Every point on the graph is shifted right 2 units.
d. Every point on the graph is shifted up 2 units.
Answer:
Step-by-step explanation:
The function translation / transformation rules: f (x) + b shifts the function b units upward. f (x) – b shifts the function b units downward. f (x + b) shifts the function b units to the left.
so it should be d
