Paolo was asked to find the original dimension of an enlarged pentagon. His solution is shown next to the pentagons.

Write a proportion.
Cross multiply.

Solve for x.
Not drawn to scale

What error did Paolo make in his solution?
Paolo set up an incorrect proportion.
Paolo made an error when he cross multiplied the proportion.
Paolo divided incorrectly when he solved for x.
Paolo multiplied instead of divided when he solved for x.

Paolo made an error when he cross multiplied the proportion

Step-by-step explanation:

The picture of the question in the attached figure

we know that

A dilation is a non rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional

In this problem the figures are similar

so

using proportion

solve for x

Multiply in cross

therefore

Paolo made an error when he cross multiplied the proportion

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for

Idrk but i think u should figure out the n dia n then the units it will make it way more easier
