Which statement is true about the polynomial 3x2y2 − 5xy2 − 3x2y2 + 2x2 after it has been fully simplified? it has 2 terms and a degree of 2. it has 2 terms and a degree of 3. it has 4 terms and a degree of 2. it has 4 terms and a degree of 4.

It has 2 terms and a degree of 3.

Step-by-step explanation:

When simplifying a polynomial like this, we combine like terms.  Like terms will be anything that has the same variables and exponents.

Looking at our polynomial, the only like terms we have are 3x²y² and -3x²y².  When we add these together we get 0; this means they cancel.  That leaves us with

-5xy² + 2x²

There are two terms left.

To find the degree of the polynomial, we find the degree of each term (the sum of the exponents).  The degree of the first term is 1+2 = 3; the degree of the second term is 2.  The degree of the polynomial is the higher of these two, so it is 3.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
