Which of the following is a trinomial?
Masja [62]
Although you didn't provide any answer choices:

A trinomial is an expression with exactly three terms that can't be combined an example would be this

x^2 - 3x + 1

None of those terms can be combined

x^2 + 3 - 4 has three terms but it isn't considered a trinomial because you can simplify it to x^2 - 1 which is known as a binomial because it has 2 terms in it's simplified form.

hope this helps C:

What is the result of −18⋅16 2/3? Enter the result as an improper fraction and as a mixed number.
hjlf

Answer:

-30000/100

300 0/1

Step-by-step explanation:

We have the following numbers -18 and 16 2/3, the first is an integer and the second is a mixed number, the first thing is to pass the mixed number to a decimal number.

16 2/3 = 16.67

We do the multiplication:

−18⋅16 2/3 = -300

We have an improper fraction is a fraction in which the numerator (top number) is greater than or equal to the denominator (bottom number), therefore it would be:

-30000/100

How mixed number would it be:

300 0/1

Why do we say that light travels in straight lines? Is it strictly accurate to say that a laser beam provides a per- fectly stra
Aliun [14]

Answer:

Step-by-step explanation:

Light is considered to be without mass, but it has energy. According to Einstein, energy can be

equivalently presented as mass. Mass is also affected by gravity, but near planets, this effect is

so small that it can be ignored and so we say that light travels in a straight line.

The above statement does not hold true when light passes near a star. A star possesses a very

high gravity field that bends light such that the change of direction is observed.
