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 you translate the following phrase to a mathematical expression the product of a number and nine?

9x


What describes a fraction that has a variable or variable expression in its numerator its denominator or both?

There is no specific name. If the numerator and denominator are polynomials in the variable then the question describes an algebraic fraction. But there is no reason at all to assume that they are polynomials. There is no specific phrase that describes sin(x)/x, for example.


This two-word phrase indicates a ratio or fraction?

It is a "rational number".


What is a mathematical phrase that has numbers and operation signs but no equals sign?

if there are no comparison signs (equals or inequalities, ie =, >, < etc) then it is an expression, eg "x + 5" If there is a comparison sign which is not equals, then it is an inequality, eg "x > 5"


What is the last number of Pi?

The last digit of piLet us re-phrase the question in a more meaningful way, "What is the final digit in expressing the value of Pi?" [Pi itself is a number.] The answer is that there is no final digit. When written as a numerical expression (3.14159 26535 89793 ...), the expression is infinitely long. Hence, there is no final digit.Pi is an irrational number [i.e. one that can not be represented as the ratio of two integers]. All irrational number have infinitely many digits when written as numerical expressions. [Many rational numbers do also, such as one-third, which is 0.3333... .] The difference is that rational numbers repeat a sequence of digits infinitely many times (such as one-eleventh, which repeats 0.09090909...).Pi is also a transcendental number, meaning that it is not the root of an algebraic equation that has rational coefficients. [By contrast, the square root of two is an irrational number, but is the solution of the algebraic equation: X2 = 2.]Pi appears in the famous "Euler's Equation" [Euler is pronounce like 'oiler'. He was a Swiss mathematician.] which is e(i*pi) +1 =0, where 'i' is the square root of -1. This equation combines five of the most important numbers in mathematics and science.
