Given:

A triangle has side lengths of (7.8v+2.6) centimeters, (5.3v+4.5) centimeters, and (2.4w-6.7) centimeters.

To find:

The expression which represents the perimeter, in centimeters, of the triangle.

Solution:

We know that

Perimeter of a triangle = Sum of length of all sides of the triangle

Perimeter=(7.8v+2.6)+(5.3v+4.5)+(2.4w-6.7)

Now, combine like terms.

Perimeter=(7.8v+5.3v)+(2.4w)+(2.6+4.5-6.7)

Perimeter=13.1v+2.4w+0.4

Therefore, the expression for perimeter, in centimeters, of the triangle is 13.1v+2.4w+0.4.

Look at the set of quadrilaterals in the coordinate plane shown below.
morpeh [17]

The true statement about the set of quadrilaterals in the coordinate plane is B. Because quadrilateral ABCD can be reflected across the x -axis, then rotated 90° counterclockwise about the origin, and then dilated about the origin by a scale factor of 2 to obtain quadrilateral A'B'C'D' , then quadrilateral ABCD is similar to quadrilateral A'B'C'D'.

<h3>What is a quadrilateral?</h3>

A quadrilateral is a polygon having four sides, four angles, and four vertices.

In this case, because quadrilateral ABCD can be reflected across the x -axis, then rotated 90° counterclockwise about the origin, and then dilated about the origin by a scale factor of 2 to obtain quadrilateral A'B'C'D' , then quadrilateral ABCD is similar to quadrilateral A'B'C'D'.
