Geometry

[prk0ur]

Ok so I have 3 questions I was wondering how to do?


ok so I have to find the value of x The problem is x(squared) + x and x(squared) + 4. I have no idea how to find the x when all the numbers given to me are 4. and what it is asking for are the sides of a square
I have no work done it since I dont know where to begin.

The second is
Is a polygon a plane figure (Always,sometimes,never) answer one of three

and the 3rd
Find x. X(squared) + 2x + 40
and x(squared) - x +190

I dont want number 1 and 3 answered only how to begin them but number 2 i dont know

find the value of x The problem is x(squared) + x and x(squared) + 4. I have no idea how to find the x when all the numbers given to me are 4. and what it is asking for are the sides of a square

Your first problem statement is unclear. Are you saying that “x^2 + x” is the length of one side of a square and that “x^2 + 4” is the length of another side of the same square? If so, then since the sides of a square are all the same length, these expressions must be equivalent:

x^2 + x = x^2 + 4

Solve for x.

The second is
Is a polygon a plane figure (Always, sometimes, never)

Do some studying. Look up definitions for “polygon” and “plane figure” in your book. If that does not work, look them up online.

Find x. X(squared) + 2x + 40
and x(squared) - x +190

Your problem statement makes no sense. What is “and” supposed to mean in this context?
