We have to add the polynomials and

To add the polynomials we need to add the like terms, by like terms we understand that the terms with the same exponent of the variables.

So in this case,

We will add the coefficients of , and constants separately, we get:

Similarly, for the polynomials

We will subtract the coefficients of like terms, we get:

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.
