Please help me:(***********​

Answer:

<em><u>A:</u></em>

<em><u>Square</u></em>

<em><u>Rectangle</u></em>

<em><u>Parallelogram</u></em>

<em><u>Quadrilateral</u></em>

<em><u>Rhombus</u></em>

<em><u></u></em>

<em><u></u></em>

Step-by-step explanation:

All sides and angles are equal so it is a square

All angles are 90 degrees so it is a rectangle (eliminate C)

Opposing angles and side lengths are congruent so it is a parallelogram (eliminate D)

It has 4 sides so it is a quadrilateral (eliminate B)

Since all of the other answers are eliminated you don't necessarily need to prove that is is a rhombus, but it is good practice.

Opposing sides are congruent so it is a rhombus.

What is true about the sum of the two polynomials?<br> 6s^2t – 2st^2<br> 4s^2t – 3st^2
Snowcat [4.5K]
The sum is 10s^2t-5st^2. With two separate sections it’s a binomial, and the sum of the powers of the variables is 2+1=3, it has a degree of 3.
