I think best word to insert in the blank is the term "bisecting".
An altitude of a triangle is a line or segment that passes through a vertex of the triangle and is bisecting <span>to the line containing the opposite side.
</span>"Bisect<span>" means to divide into two equal parts which is true for the altitude of a triangle.</span>
1/7 of the dominoes will have the same number on both sides
1) What left
![\boxed {d-22 \geq 42}](https://tex.z-dn.net/?f=%5Cboxed%20%7Bd-22%20%5Cgeq%2042%7D)
*Obs: remember that left at least 42 dollars. In other words, the left over is equal or more than 42 dollars.
2) At the beginning
Letter C
36*40+36*40-6*6=2844ft^2
we had to subtract the area of the closet so it wasn't counted twice :P
