Adeli charges the same price, $5.50, for all of its different sandwiches. if a company ordered n sandwiches for a luncheon, which equation could be used to find the total price, p, that the deli charged for the sandwiches? a- n/5.50=p b-5.50n=p c-5.50/n=p d-5.50+n=p

Write the expression as a constant , a single trigonometric function, or a power of a trigonometric function. sin x cos x/ tan x

The diagonals of a quadrilaretral intersect at (-1,4). one of the sides of the quadrilateral is bounded by (2,7) and (-3,5) determine the coordinates of the other side in order for the quadrilaretral to be a square.
