Let p be the set of polynomials let a, b,c be elements ofn0 such that b and d are non zero elements of p which of the following is true regarding the sum below

rational expression

Step-by-step explanation:

A. The sum is a rational expression

Step-by-step explanation:

we are given

we are given that

'b' and 'd' are non-zero values

So,

a/b is a rational number

c/d is a rational number

we can see that both are added

So, sum of rational expression is also a rational expression

so,

A. The sum is a rational expression

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
