Answer:
Perimeter = 6x-8
Step-by-step explanation:
a=x+5
b=2x-9
Perimeter = 2*(a+b)
Perimeter = 2*(x+5+(2x-9))
Perimeter = 2*(x+5+2x-9)
Perimeter = 2*(3x-4)
Perimeter = 6x-8

Answer:
[tex]T_n = 2n -3[/tex]
Step-by-step explanation:
Given
[tex]S_n = n^2- 2n[/tex]
[tex]T_n = S_n - S_{n-1[/tex]
Required
Find [tex]T_n[/tex]
[tex]S_n = n^2- 2n[/tex]
Calculate [tex]S_{n-1[/tex]
[tex]S_{n-1} = (n-1)^2- 2(n-1)[/tex]
[tex]S_{n-1} = n^2-2n+1- 2n+2[/tex]
[tex]S_{n-1} = n^2-2n- 2n+1+2[/tex]
[tex]S_{n-1} = n^2-4n+3[/tex]
[tex]T_n = S_n - S_{n-1[/tex] becomes
[tex]T_n = n^2 - 2n - (n^2 - 4n +3)[/tex]
[tex]T_n = n^2 - 2n - n^2 + 4n -3[/tex]
[tex]T_n = n^2 - n^2- 2n + 4n -3[/tex]
[tex]T_n = 2n -3[/tex]
Quadratic formula 3x^2 - 2x + 5 = 0
Step-by-step explanation:
The given quadratic equation is :
[tex]3x^2 - 2x + 5 = 0[/tex]
We need to solve the given equation. The formula used to solve a quadratic equation is :
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
We have, a = 3, b = -2 and c = 5
So,
[tex]x=\dfrac{-(-2)\pm \sqrt{(-2)^2-4(3)(5)}}{2(3)}\\\\x=0.333,4.667[/tex]
Hence, this is the required solution.

[tex]3= \frac{f}{6} -1[/tex]
Answer:
f=24
Step-by-step explanation:
3 = f/6 - 1
Multiply both sides of the equation by 6.
18=f−6
Swap sides so that all variable terms are on the left hand side.
f−6=18
Add 6 to both sides.
f=18+6
Add 18 and 6 to get 24.
f=24
Which group contains triangles that are similar. im having a hard time

Step-by-step explanation:

In the figure below,
Answer:
m<GLK = 58°
Step-by-step explanation:
Given:
m<GLH = 2x + 6
m<HLJ = x
Required:
m<GLK
Solution:
First, find the value of x
m<GLH + m<HLJ = 180° => Linear Pair Theorem
Substitute
2x + 6 + x = 180
Add like terms
3x + 6 = 180
3x + 6 - 6 = 180 - 6
3x = 174
3x/3 = 174/3
x = 58
m<HLJ = x = 58°
Thus, m<HLJ and m<GLK are Vertical angles.
Therefore:
m<GLK = m<HLJ (Vertical angles theorem)
m<GLK = 58° (Substitution)

a rectangular prism with a volume of 10 cubic units is filled with cubes with side lenghts of 1/2 unit how many 1/2 unit cubes does it take to fill the prism
Answer:
Step-by-step explanation:
The volume of a cube is
V=s^3, we are told the volume is 10u^3 and that it will be filled with cubes having a side of 1/2 so
n(1/2)^3=10, where n will be the number of these small cubes
n(1/8)=10 upon multiplying each side by 8
n=80
So it will take 80 cubes of side length 1/2 to have a volume equal to 10u^3

Find the volume of the composite figure. First, find the volume of the triangular prism. 4 cm Triangular prism Volume = [?] cm 5 cm 5 cm 6 cm Rectangular prism Volume = [ ] cm? 10 cm Total Volume of Composite Figure = [ ]cm 8 cm Enter
Answer: See attached image.
The total volume of the composite figure is 530 cm³.
To find the volume of the composite figure, we need to calculate the volumes of the individual prisms and then add them together.
Triangular Prism:
The volume of a triangular prism is given by the formula:
Volume = base area × height
The base of the triangular prism is a triangle with a base of 5 cm and a height of 5 cm.
Therefore, the base area is:
Base area = (1/2) × base × height = (1/2) × 5 cm × 5 cm = 12.5 cm².
Now, we can calculate the volume of the triangular prism:
Triangular prism volume = base area × height = 12.5 cm² × 4 cm = 50 cm³.
So, the volume of the triangular prism is 50 cm³.
Rectangular Prism:
The volume of a rectangular prism is given by the formula:
Volume = length × width × height.
Given the dimensions of the rectangular prism as length = 6 cm, width = 10 cm, and height = 8 cm, we can calculate its volume:
Rectangular prism volume = length × width × height = 6 cm × 10 cm × 8 cm = 480 cm³.
So, the volume of the rectangular prism is 480 cm³.
Total Volume of Composite Figure:
To find the total volume of the composite figure, we add the volumes of the individual prisms:
Total Volume = Triangular prism volume + Rectangular prism volume = 50 cm³ + 480 cm³ = 530 cm³.
Therefore, the total volume of the composite figure is 530 cm³.

Jasmine began completing the table below to represent a particular linear function.
a. Complete the table and find the rate of change for the function
Rate of change:
b. Create a graph and write an equation to represent this function
Answer:
Step-by-step explanation:
Rate of change = Slope of line
Use the coordinates of two points to find the slope of the line.
Slope of line through (2,5) and (0,1) = (5-1)/(2-0) = 2
(0,1) is a point on the line, so the y-intercept is 1.
Slope-intercept equation of the line: y = 2x+1
Use the equation to fill in the rest of the table:
x = -2, y = -3
x = ½, y = 2
x = 1, y = 3
x = 3, y = 7
