Nancy and her sister went to the store together. After the store, Nancy walked 2 blocks west to get a coffee and her sister walked 7 blocks west back to work. How many blocks is the coffee shop that Nancy went to from her sister's work?

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

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.
