To find the perimeter of a triangle you have to add up all the sides. So to find the perimeter of this triangle you just add 2x+5x+6x=13x. To find the actual perimeter you would have to know what x equals

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

How do find the perimeter of a triangle?

The easiest way is if you already have the lengths of all three sides of the triangle. In which case, you simply add their lengths together to acquire the perimeter. However, if you only have the lengths of two sides of a triangle, and it's a right triangle"; you can use the Pythagorean Theorem to determine the length of the third side. Note: Here are some quick definitions of terms that will be used in the following equations. A² will represent the height of the triangle. B² will represent the width of the triangle. C² will represent the hypotenuse of the triangle. The "Hypotenuse" is the longest side of a triangle. A "Right Triangle" is a triangle that has an angle measuring 90°. When using the Pythagorean Theorem; if you're attempting to find hypotenuse of a triangle; you use the formula "A² + B² = C²". That is; you square the two known sides; then add the products. Upon doing that, find the square root of the sum of both numbers, and you have the length of the hypotenuse. Upon finding the missing side's length; add the lengths of all three sides, and the resulting number will be the perimeter of the triangle. If you have the length of one side, and the hypotenuse of a right triangle; and are seeking to find the third side's length; you use the formula "C² - A² = B²" or "C² - B² = A²"; depending on which side your attempting to find the length of. Like in the previous equation, add the lengths of all three sides together to acquire the perimeter.


What does a isosceles triangle look like?

It looks like a triangle that has two sides that are the same length.


How do you find perimeter of a triangle with a number like x?

What kind of triangle? if it's an equilateral triangle, then all the sides are of equal length, and the perimeter (all the way around) would be the sum of the three sides. If one side equalled x in length, then the perimeter would be 3x. This only works for equilateral triangles (all three angles are 60 degrees because the sum of the angles of a triangle is 180, and 180/3=60), which is why you need to specify what kind of triangle you are talking about. Right triangles have one angle which is 90 degrees...... I'm guessing your textbook has more info on this. You might want to refer to it. However, since you asked how you FIND the answer rather than what is the answer to.... I'm willing to help some. :) Good luck.


How to find perimeter?

In order to find the perimeter you need to know how to add of course like if you have a square and the area is 11.6 you have to add up all the sides in a aquare which is 4 then you add 11.6 four times which gives you the answers of 46.4If you want to find the perimeter, you just have to add the the sides together. For example, if you are measuring the perimeter for a square (with equal sides) then you just have to find the length for one side and multiply it by four. If you want to do it for an irregular square, then you add the length of the sides together. In algebra, they sometimes make you find the length of a side giving you the whole perimeter and the measurement of one or a few other sides, but they might leave one side as x or y or any other variable. You can find the perimeter for any shape. Perimeter is also shown in word problems. Most of the time, they represent perimeter by a fence. Some people mistake perimeter and area. Just remember, area is the inside and perimeter is the outside. I hope I helped!


How are an equilateral triangle and a scalene triangle a like?

They both have 3 sides They both have 3 interior angles that add up to 180 degrees They both have no diagonals They both have a perimeter which is the sum of their 3 sides They both will tessellate They both have an area which is 0.5*base*height

If a garden is shaped like an equilateral triangle and the perimeter is 36 ft how long in ft is one side of the garden?

Perimeter: total length of the shape, 36 ft.Equilateral Triangle: a shape with 3 sides, each equal in measure.36 ft/3 sides = 12 ft in length for one side (and for each of the other sides) of the garden.


How does a triangle with no sides look like?

There is no such thing as a triangle with no sides. Every triangle must have at least three sides. The only shapes with no sides are an oval and a circle.

How do i write an expression for the perimeter?

To calculate the perimeter, by definition, you must add up all the sides. The details, of course, vary from case to case. For example, if you have an arbitrary triangle, the expression would be something like side1 + side2 + side3 (or whatever the sides are called). In some cases you can simplify the resulting expression; in an isosceles triangle, you have two equal sides, so you get an expression similar to a + a + b = 2a + b. In a rectangle, opposite sides are equal, so you get perimeter = a + b + a + b = 2a + 2b or 2 (a + b).
