(x^2 - 4x) + (y^2 + 8y) = -4

Since the width is 8, and there are two widths that is 16 inches. 26-16 is 10. so you have to split 10 so you will have two even sides. which is 5. so it is b.i hope this you.

To begin, it's a resizing (or more specifically, a dilation), which means all the angles are still the same, so all of the sides and such are still in proportion. because similar objects are said to have corresponding sides and angles, and the shapes follow that rule, they are similar.you could even create the same shape if you divide all of the sides of the first shape by 2 and translating it.to summarize: they contain the same angles and the proportions of the sides, so they're similar.
