Question

Choose the polynomial that is written in standard form.

xy3 + 4x5y + 10x3

x4y2 + 4x2y + 8x

-9x4y2 + 4x3y5 + 10x2

x6y3 + 4x4y8 + x2

Answer 2

@jim_thompson5910 No sir. Not a clue.

Answer 3

to find the degree of something like xy^3, you add the exponents

Answer 4

So the degree of 2x^4+5xy^2= 6?

Answer 5

no you add the exponents for the monomial

Answer 6

degree of 2x^4 is 4

degree of 5xy^2 is 3 (since 1+2 = 3)

Answer 7

5xy^2 is the same as 5x^1y^2

add the exponents: 1+2 = 3

degree of 5xy^2 is 3

Answer 8

What's the degree of 4x^5y ?

Answer 9

7?

Answer 10

Wait no 6.

Answer 11

good, 5+1 = 6

Answer 12

find the degree of each monomial

Answer 13

the polynomial where you have the degrees decrease is the one written in standard form

Answer 14

So in this particular case the answer would be D?

Answer 15

Can you help me with another?

Answer 16

Notice

x^6y^3 has degree: 6+3 = 9

4x^4y^8 has degree: 4+8 = 12

so choice D is not the answer because the degrees are supposed to decrease

Answer 17

Ohhhh so B?

Answer 18

much better

Answer 19

Okay great! Thank you so much!! Can you help me with another one please sir?

Answer 20

sure, what's your question?

Answer 21

Simplify: (6x2 - 3 + 5x3) - (4x3 - 2x2 - 16)

2x3 - x2 + 21

-2x3 + x2 - 21

x3 + 8x2 + 13

-x3 - 8x2 + 13

Answer 22

I put C and was hoping you could verify.

Answer 23

C is correct

Answer 24

Great! Thanks!! You dont know how much I appreciate that!!
