Which expression is not a polynomial?
Nezavi [6.7K]

Answer:

D.

Step-by-step explanation:

A term in a polynomial is a single number or a number multiplied by any number of variables. A polynomial is a sum of terms.

The only thing that can be done with variables in a polynomial is to multiply them by numbers or other variables. In a polynomial, you cannot: divide by a variable (have a variable in a denominator), have a root of a variable, have a log of a variable, have a variable as an exponent, etc.

All expressions are polynomials except for D. In D., the negative exponents mean division by variables.

A carpenter built a square table with side length x. Next, he will build a rectangular table by tripling one side and halving th
mart [117]

The simplified expression for the area of the rectangular table is Three-halves x squared, 3x²/2

<h3>What is the area of the rectangular table?</h3>

Since the carpenter built a square table with side length x.  Next, he will build a rectangular table by tripling one side and halving the other.

To find the area of the rectangular table, we know that Area, A = LW where

  • L = length and
  • W = width

Now, since the length of the square is x, and the rectangular table has one side of the square tripled and halving the other side .

So,

let

  • length of the rectangular table = L = x/2 and
  • width of rectangular = W = 3x

So, the area of the rectangular table A = LW

= x/2 × 3x

= 3x²/2

So, the simplified expression for the area of the rectangular table is Three-halves x squared, 3x²/2

A person has 100 notes of Rs. 10 and Rs. 20 each. He went to a shop and bought items for Rs. 220. In how many ways can he pay th
Alekssandra [29.7K]

There are 12 ways he can pay this amount using the notes he has the answer is 12.

<h3>What are permutation and combination?</h3>

A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

Let x be the number of Rs10 notes and y be the Rs20 note

10x + 20y = 220

The whole number of x and y which satisfy the above equation:

x = 0, y =11

x = 2, y =10

x = 4, y =9

x = 6, y =8

x = 8, y =7

x = 10, y =6

x = 12, y =5

x = 14, y =4

x = 16, y =3

x = 18, y =2

x = 20, y =1

x = 22, y =0

Total number of ways = 12

Thus, there are 12 ways he can pay this amount using the notes he has the answer is 12.
