Which expression is a factor of

9x +12 xy + 4y??

3x³ + 2y

Step-by-step explanation:

We use sum of squares to factor out the expression:

(3x³ + 2y)²

In that case, we look for the answer choice with 3x³ + 2y as a factor. We should get the 3rd Choice as our answer.

C. 3x^3 + 2y

Step-by-step explanation:

9x^6 + 12x^3y + 4y^2

9x^6 = (3x^3)^2

4y^2 = (2y)^2

So far it looks like the trinomial can be the square of a binomial. We need to check the middle term.

2 * 3x^3 * 2y = 12x^3y

The middle term checks out, so this trinomial is a perfect square trinomial.

9x^6 + 12x^3y + 4y^2 = (3x^3 + 2y)^2

C. 3x^3 + 2y

the correct answer is x/3+10≥32

hope this !

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
