*Demonic high pitch scream* Planes A and B intersect.

Vertical plane B intersections horizontal plane A at line k. Line k contains points Y and Z. Line m intersects line n at point W.

Which describes the intersection of line m and line n?

point W
point X
point Y
point Z

Step-by-step explanation:

"Line m intersects line n at point Wintersection of line m and line n?"

The answer is already given which is point W.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
