Sadiir took a math test and got 10 incorrect answers and 40 correct answers.

40 answers+ 10 answers = 50 answers.

40 (correct) answers/ 50 (total) answers *100% = 80%.

The correct answer is c. 80 percent.

Hope this helps~

Will give brainly .Which statements are true regarding undefinable terms in geometry? Check all that apply.
babymother [125]

The true statements about terms in geometry that are undefinable are;

  • A point has no length or width
  • A point indicates a location on the coordinate plane
  • A line consists of an infinite set of points.
  • A plane consists of an infinite set of points.

<h3>How can the true statements be found?</h3>

Three undefinable terms in geometry are;

1) Point

2) Line

3) Plane

The above terms do not have a formal definition but they can be described based on their properties.

The other geometric terms are defined based on the above undefinable terms.

A point can be described as a location in space that is dimensionless and can be specified on the coordinate plane as an ordered pairs (x, y).

True statements about a point are therefore;

  • A point has no length or width
  • A point indicates a location on the coordinate plane

A line is infinitely long, that has no beginning or end. It has one dimension, with no thickness or height.

Given that a point is dimensionless, a line can be considered a set of points.

A true statement is therefore;

  • A line consists of an infinite set of points.

A plane is a two dimensional geometric figure that have infinite length and width.

An infinite set of lines that forms a two dimensional figure can be used to describe a plane.

The true statement with regards to a plane is therefore;

  • A plane consists of an infinite set of points.

babunello [35]

Answer:

The quotient = 2x - 1 and the remainder = 4x + 2

Step-by-step explanation:

\frac{2x^{3}+5x^{2}-7x+6}{x^{2}+3x-4}=2x+\frac{-x^{2}+x+6}{x^{2}+3x-4}

\frac{-x^{2}+x+6 }{x^{2}+3x-4}=-1+\frac{4x+2}{x^{2}+3x-4}

The quotient = 2x - 1 and the remainder = 4x + 2
