Answer: A vertex contains an infinite number of points, and a point does not have width or depth.
Step-by-step explanation:
I got this. Bottom of the triangle. that flat line is 180 degrees. you have an angle of 120, leaving an angle of 60. if you look at the top, that angle matches the other. so you have 65 degrees on one side, and 60 on the other. so 180-65-60=55. so X=55
Answer:

Step-by-step explanation:
The side length of a square is represented by the expression 2x + 5.
The area of a square is given as:

where a = length of side of the square
The area of the square is therefore:

The perimeter of a square is given as:

The perimeter of the square is therefore:

The difference between the area of the square and the perimeter of the square is:

The expression that represents the difference between the area and the perimeter of the square is:

Answer:
x = - 3 and x = 1
Step-by-step explanation:
Given the rational expression

The denominator of the expression cannot be zero as this would make the expression undefined. Equating the denominator to zero and solving gives the values that x cannot be, that is
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
Thus x = 1 and x = - 3 are both excluded values
Just follow this operation.
Find the two perfectly squared factors the multiple to your number.
Take the square root of those perfect factors then multiple them.
