Question

Which shows like terms from the expression? 9 + 5 + 7x2 + 3 x2y + 2x2 3 x2y and 2x2 7x2, 3 x2y, and 2x2 9 and 5 2, 3, 5, and 9

Answer 1

Answer:

9 and 5.

Step-by-step explanation:

So we have the expression:

$9+5+7x^2+3x^2y+2x^2$

In order to combine like terms, the variables must be exactly the same: not one less, not one more.

3x²y and 2x² cannot be combined because the first value has a y.

7x², 3x²y, and 2x² also cannot be combined because the second value has a y.

9 and 5 is the only one that can be combined because they are just integers. They can be added to be 14.

2, 3, 5, and 9 cannot be combined because the 2 and the 3 are tied to the variables as coefficients. They are not constants.

Answer 2

To combine like terms, we can combine numbers with the same power and variables.

We are given the equation: 9 + 5 + 7x^2 + 3x^2y + 2x^2

We can combine 9 and 5 because they are whole numbers by themselves.

We can combine 7x^2 and 2x^2 because they are whole numbers that both have a variable (x) and the same power.

We can't combine anything to 3x^2y because no other number has these features.

Best of Luck!
