=0.56x−0.25n=0.20x−0.03

katovenus [111]

Given:

$m=0.56x-0.25$

$n=0.20x-0.03$

To find:

The sum of m and n.

Solution:

We have,

$m=0.56x-0.25$

$n=0.20x-0.03$

The sum of m and n is:

$m+n=(0.56x-0.25)+(0.20x-0.03)$

Combining the like terms, we get

$m+n=(0.56x+0.20x)+(-0.25-0.03)$

$m+n=(0.76x)+(-0.28)$

$m+n=0.76x-0.28$

Therefore, the sum of m and n is $m+n=0.76x-0.28$ .

Is 2x and 5x^2 like terms?

ki77a [65]

No, they are not like terms because they cannot be added together. 5x^2 is squared, whereas 2x is not. Though they both have x variables attached to them, they are not like terms because one is squared and the other is not. Examples of like terms include 5 and 8, 4y and 7y, 8z^2 and 10z^2.

Hope this helps!! :)
