Answer:
Hexagon
Step-by-step explanation:
If in a regular polygon, each interior angle = 120 deg, then each exterior angle = 180–120 = 60 deg. So the polygon has 360 deg/60 deg = 6 sides. The figure is a regular hexagon.

Which of the equations are true identities? A. N ( n − 2 ) ( n + 2 ) = n 3 − 4 n B. ( x + 1 ) 2 − 2 x + y 2 = x 2 + y 2 + 1
Answer:
Both A and B are true identities
Step-by-step explanation:
A. N ( n − 2 ) ( n + 2 ) = n 3 − 4 n
We need to show that (left-hand-side)L.H.S = R.H.S (right-hand-side)
So,
n ( n − 2 ) ( n + 2 ) = n(n² - 2²) (difference of two squares)
= n³ - 2²n (expanding the brackets)
= n³ - 4n (simplifying)
So, L.H.S = R.H.S
B. ( x + 1 )² − 2x + y² = x² + y² + 1
We need to show that (left-hand-side)L.H.S = R.H.S (right-hand-side)
So,
( x + 1 )² − 2x + y² = x² + 2x + 1 - 2x + y² (expanding the brackets)
= x² + 2x - 2x + 1 + y² (collecting like terms)
= x² + 1 + y²
= x² + y² + 1 (re-arranging)
So, L.H.S = R.H.S
So, both A and B are true identities since we have been able to show that L.H.S = R.H.S in both situations.
Trey has plastic cubes stored in a box that measures 4 ft long, 2 1/2 ft wide, and 2 ft tall.
The edge length of each plastic cube is 1/2 ft.
please answer fast!!!
How many plastic cubes can fit into the box?
20 plastic cubes
45 plastic cubes
125 plastic cubes
160 plastic cubes
Answer:
160 plastic cubes
Step-by-step explanation:
first find the volume the box can hold so,
4 x 2.5 x 2 = 20ft^3
from their find the volume of each plastic cube so,
.5 x .5 x .5 = .125ft^3
then you can divide the volume of the box by the volume of the plastic cube to see how many will fit
20 ÷ 0.125 = 160 plastic cubes
Answer:
160 ;)

the graph of f(x)=ax^2 opens upward and is narrower than the graph of f(x)=x^2. which of the following could be the value of a?
A. -6
B. -0.7
C.0.4
D.3
The value of "a" for a narrow graph will be equal to 7.
What is a graph?A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
GIven functions are:-
f(x) = ax²
f(x) = 7
At the value of a=7 the graph of function f(x) = 7x² opens upward and is narrower than the graph of f(x) = x².
Hence the value of "a" for a narrow graph will be equal to 7.

Siera has 11.5 yards of yarn. She uses a certain amount for a project, leaving 5.25 yards of yarn. The equation 11.5 - x = 5.25 represents this situation, where x is the amount of yarn Siera used for her project.
Answer: 5.25 + 11.5 = 16.75 so the reverse would be 16.75 - 11.5 = 5.25

0.12 is a decimal and 12/100 or 12% is the percentage for 48/400.
Step-by-step explanation:
A fraction consists of two numbers and a fraction bar:

Answer: lesser x = 3.76 & greater x = 8.24
Step-by-step explanation: just took the test
For the given quadratic equation lesser x=3.765 and greater x=8.235.
The given quadratic equation is (x-6)²-5=0.
We need to find the solutions from least to greatest.
What is the formula to find the solution to the quadratic equation?The formula to find the solution to the quadratic equation is [tex]x=\frac{-b\pm\sqrt{b^{2}-4ac }}{2a}[/tex].
Now, (x-6)²-5=0 can be written as x²-12x+31=0
Here, a=1, b=-12 and c=31
x=(12±√20)/2
⇒x=(12±4.47)/2
⇒x=3.765 or x=8.235
Therefore, lesser x=3.765 and greater x=8.235.
