C, A

Step-by-step explanation:

First question:

As you can see the shape we're working with here is a pyramid and we must first understand that the 4 sides of a pyramid are triangles and the base of the pyramid is a square.

As shown in the picture, the cut is going horizontally through the same place the base is, so therefore, the shape the cross section would make would be a square. (c)

Second question:

Same shape; different size.

We're still working with a pyramid here, just that the base is bigger.

We can see how that the cut is going vertically through the middle of the triangle, parallel to it's side, which I mentioned earlier is a triangle

Therefore, the shape of this cross section would be a triangle. (a)

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
