. Simplify an expression for the perimeter of the equilateral triangle shown below.

Answers

Answer:

1.75×2-2

Step-by-step explanation:

look at the answer

The perimeter of the equilateral triangle with side length 1.75x - 2 is 5.25x - 6.

What is Perimeter?

Perimeter of a geometrical shape is defined as the total boundary length. The perimeter of a shape can be calculated by adding the length of all the sides.

Perimeter of regular shape can be calculated by multiplying the length of the side with the total number of sides since a regular shape has all sides equal.

Here, we have an equilateral triangle with length of a side = 1.75x - 2.

Equilateral triangle is a regular shape, with all it's sides are equal.

Perimeter of an equilateral triangle with side length x is 3x.

Therefore,

Perimeter of this triangle = 3 ( 1.75x - 2 )

By distributive property, a (b + c) = ab + ac.

Perimeter = (3 × 1.75x) - (3 × 2)

                = 5.25x - 6

Hence the perimeter of the equilateral triangle shown is  1.75x - 2.

Which expression best defines a rational number?

B. has a decimal form that cannot be rounded
C. has a decimal form that is terminating or repeating
D. has a decimal form that is nonterminating and nonrepeating

Answers

A for sure because it can be

Rational numbers are terminating or repeating numbers. Therefore, option C is the correct answer.

We need to check from the options which expression best defines a rational number.

What are rational numbers?

Rational numbers: Rational numbers are in the form of p/q, where p and q can be any integer and q ≠ 0. This means that rational numbers include natural numbers, whole numbers, integers, fractions of integers, and decimals (terminating decimals and recurring decimals).

Rational numbers can be easily identified with the help of the following characteristics.

All integers, whole numbers, natural numbers, and fractions with integers are rational numbers.If the decimal form of the number is terminating or recurring as in the case of 5.6 or 2.141414, we know that they are rational numbers.In case, the decimals seem to be never-ending or non-recurring, then these are called irrational numbers.

So, from the definition, we understood that rational numbers are terminating or repeating numbers.

Therefore, option C is the correct answer.
