Answer:
x² + 18x +81
x² - 14x +49
4x²- 4x - 1
Step-by-step explanation:
multiply the x in the first parentheses by x and 9 in the other parentheses and
multiply the 9 in the first parentheses by x and 9 in the other parentheses and add all together
(x+9)(x+9)
x² + 9x + 9x + 81
x² + 18x +81
multiply the x in the first parentheses by x and -7 in the other parentheses and multiply the -7 in the first parentheses by x and -7 in the other parentheses and add all together
(x-7)(x-7)
x² -7x - 7x +49
x² - 14x +49
(2x-1)² is the same as (2x-1)(2x-1)
multiply the 2x in the first parentheses by 2x and -1 in the other parentheses and multiply the -1 in the first parentheses by 2x and -1 in the other parentheses and add all together
(2x-1)(2x-1)
4x²-2x-2x+1
4x²- 4x - 1

Answer:
Options (1), (3) and (5)
Step-by-step explanation:
Coordinates of D → (2, 2)
Coordinates of E → (1, 6)
Coordinates of F → (5, 7)
Coordinates of G → (6, 3)
Length of ED = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
= [tex]\sqrt{(2-1)^2+(2-6)^2}[/tex]
= [tex]\sqrt{17}[/tex]
Length of FG = [tex]\sqrt{(5-6)^2+(7-3)^2}[/tex]
= [tex]\sqrt{17}[/tex]
Length of GD = [tex]\sqrt{6-2)^2+(3-2)^2}[/tex]
= [tex]\sqrt{17}[/tex]
Length of EF = [tex]\sqrt{(1-5)^2+(6-7)^2}[/tex]
= [tex]=\sqrt{17}[/tex]
Since, all sides of the given quadrilateral are equal in length, quadrilateral will be a square.
Therefore, diagonals EG and DF will be perpendicular, equal in measure, congruent and will bisect each other.
Options (1), (3) and (5) are the correct options.

Write an equation for the hanger diagram and then us the sketch to show how to solve the equation algebraically.
Answers
Step-by-step explanation:
Since there are 3 w's and a 1 on one side and 7 1's on the other and the hanger diagram shows they are even, we can set them equal to each other.
3w + 1 = 7 Subtract 1 from both sides
3w = 6 Divide 3 from both sides
w = 2

376.99 cm^3 or 120π cm^3
Step-by-step explanation:
The volume of a cone is 1/3(B*h) where B is the base area and h is height.
The base of a cone is a circle.
Area of a circle=πr^2
Area of the circle=π6^2
Area of the circle=36π
Plug it into the formula for the volume:
V=1/3(36π*10)
V=1/3(360π)
V=120π
V=376.99
