What needs to be corrected in the following construction for copying ∠abc with point d as the vertex?

From looking at both the pictures shown for the problems which can be found in the attachment below. I concluded that what needs to be corrected in the following construction for copying ∠ABC with point D as the vertex is answer choice:

C) The third arc should cross the second arc.

I hope this helps, Regards.

The third arc should cross the second arc.

third option: 6x+8

step-by-step explanation:

we can see that the given question is a sum of series and the values of n vary from 0 to 3

the first term will be:

when n=0, [(0)*x+2] => (0+2) => 2

when n=1, [(1)*x+2] => (x+2) => x+2

when n=2, [(2)*x+2] => 2x+2

when n=4, [(3)*x+2] => 3x+2

so adding up all the terms will give us:

=2+x+2+2x+2+3x+2

=x+2x+3x+2+2+2+2

=6x+8

so,

third option is the correct answer ..
