Answer:

x^3y and  x^2y^2

Step-by-step explanation:

An algebraic expression is a polynomial if and only if the variables involve have positive integral indices or exponents.

The given polynomial is: 8x^3y^2----------+3xy^2

We want to put one of the following polynomials in the blank space to create a fully simplified polynomial written in standard form.

-4y^3

x^2y^2

x^3y

7x^2y

7x^0y^3

A fully simplified polynomial written in standard form is obtained by writing the simplified polynomial in decreasing order according to degree.

Since the first term of  8x^3y^2----------+3xy^2 having a degree of 5 and the last term is having a degree of 3.

The polynomial that goes into the blank must have a degree of 4.

This eliminates -4y^3, 7x^2y

and 7x^0y^3

We are now left with x^2y^2 and x^3y

The required polynomial is therefore 8x^3y^2-x^2y^2+3xy^2 or8x^3y^2-x^3y+3xy^2

These two polynomials are in standard form and cannot be simplified further.

The correct choices are;

x^3y and  x^2y^2

What is the closest perfect square greater than 54
Anna35 [415]

Answer:

64

Step-by-step explanation:

Perfect squares are integers multiplied by themselves.

  • 2 times 2  = 4
  • 3 times 3  = 9
  • 4 times 4  = 15

The closest perfect squares to 54 are 49 (7^2) and 64 (8^2).

49 is less than 54, so that's ruled out.

Therefore, the closest perfect square to 54 that is greater than it is 64.

Thr four angles of a quadrilateral L are in the ratio 5:2:3:8find the angle
Anuta_ua [19.1K]
Ratio = 5:2:3:8
Sum of all internal angles = 360°
5x + 2x + 3x + 8x = 360°
18x = 360°
x = 20°
Therefore,
5x = 100°
2x = 40°
3x = 60°
8x = 160°
5:2:3:8 :: 100:40:60:160.
