Hey user!
your answer is here..
we know about EULER'S FORMULA, it is a formula used to verify a polyhedron or to calculate the number of faces, vertices or edges.
Euler's formula = F + V - E = 2
given :-
faces = 28, verticies = 50 and edge = ?
we know that F + V - E = 2
therefore 28 + 40 - E = 2
==> 68 - E = 2
==> - E = 2 - 68
==> - E = - 66
==> E = 66
hence, the number of edges of the polyhedron is 66.
cheers!!
We can set Maggie's age to x
If her brother is six years younger than four times her age, than her brother must be equal to: 4x-6
Since the sum of their ages is 39, we can set up an equation.
(Sum of Maggie's age) + (sum of Maggie's brother's age) = 39
x + (4x -6) = 39
5x -6 = 39
5x = 45
x = 9 , Maggie's age is 9
Answer:
Sqrt of 6 = 2.449… round = 2.4 is less than 2.5

Answer:
The graph of 
is also attached below, which indicates that there is a change of only one unit on the y-axis for every two units of x-values.
Step-by-step explanation:
When there is a change in x values, it is basically a horizontal change. horizontal change between two values is also called the run.
And the vertically change between two values is also called the rise.
The slope is basically the ratio of the vertical (rise) and horizontal (run) changes between two points on a line.
For example, consider the equation
Here fore every two units of x-values, one units are moved on the y-axis.
In other words, there is a change of only one unit on the y-axis for every two units of x-values.
The graph of is also attached below which is showing this.
