Answer:
87.6
Step-by-step explanation:
The answer is 2x-26
1+2x-27 9*3= 27
1-27+2x You would combine like terms here
2x-26
Similar polygons only differ by a scaling factor. In other words, two polygons are similar if one is the scaled version of the other.
In particular, this implies that the angles are preserved, and the correspondent sides are in proportion.
These two polygons are both rectangles, so the angles are preserved. We must check the sides, and we have to check if the smaller sides are in the same proportion as the bigger sides.
So, the two rectangles are similar if the following is true.

In any proportion, the product of the inner terms must be the same as the product of the outer terms:

This is clearly false, and thus the two rectangles are not similar.
15$ I believe, as we can disregard the two original books (they have been payed for) leaving her to buy 1 book and having seven dollars, however if she needs $8 more you simply need to add 8+7.
Answer:
Cylinder Surface Area = (2 • π • r²) + (2 • π • r • height)
Surface Area = (2 * PI * 7^2) + (2*PI*7*22)
Surface Area = 307.8760800518 + 967.6105373057
Surface Area = 1,275.4866173575 Square Inches
Cylinder Volume = π • r² • height
Volume = PI * 7^2 * 22
Volume = 3,386.6368805698 Cubic Inches
Surface Area to Volume = 1,275.4866173575 / 3,386.6368805698 =
0.3766233766
