1=x-8
add 8 to both sides
9=x

checking that it works
1=9-8
1=1
so 9=x

The lengths of the sides of a triangle are 11.25 inches, 9.25 inches, and 10.25 inches. What is the perimeter of the triangle?
solong [7]

Perimeter of the triangle is 30.75 inches.

Step-by-step explanation:

  • Step 1: Given sides of the triangle = 11.25 in, 9.25 in, 10.25 in
  • Step 2: Formula for perimeter of triangle = length of sides of the triangle
  • Step 3: Substitute in the formula

Perimeter = 11.25 + 9.25 + 10.25

= 30.75 inches

if we're factoring you can use the AC method. A multiplied by C is 24. and 4x6 is 24.

(x+4)(x+6) is your answer

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.
