Which algebraic expressions are polynomials? Check all that apply.
+ 5y - B
02-

In the above Question both  are the Polynomials.

Step-by-step explanation:

Polynomial : These are the algebraic expressions that are formed using variables and numbers, in the polynomial we use arithmetic expressions such as addition,subtraction,division,exponentiation,multiplication and etc. A polynomial is made by adding or subtracting the terms.

While ,

       a)     is a Polynomial .

            it consists of two unlike terms so it is a binomial .

       b)   02 -  is also a Polynomial.

              it consists of only one term so it is a monomial.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
