Step-by-step explanation:
To find the area of a triangle where you know the x and y coordinates of the three vertices, you'll need to use the coordinate geometry formula: area = the absolute value of Ax(By - Cy) + Bx(Cy - Ay) + Cx(Ay - By) divided by 2. This can help you do it.
If the perimeter is 100, the sum of the length and the width is 100/2=50. Thus, the width is 50-35=15 feet.
Find the indicated intersection or union {q, s, u, v, w, x, y, z} ∪ {q, s, y, z}

The union of two sets combines the members of both sets. The elements
already belong to the first set, so the intersection is just
Other numbers will have to be 1, 2, and 4 because they are all factors of 8.
