Slope = (-3 - r) / (2 - 5)
Slope = <span>(-3 - r) / -3 = 4/3
-(-3 - r) = 4
3 + r = 4
r = 4 - 3
r = 1 option b.</span>
6a+16
Explanation:
If there's just a variable, there's an understood 1 in front of it. So what that really says is:
7a-1a+16
So, you combine the a's. 7a minus 1a is 6a. Same as 7-1,but you have a variable stuck on the end of it.
6a+16

Answer:
dont u have the answer
Step-by-step explanation:
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.
![4\div 5 = 11\div 12](https://tex.z-dn.net/?f=4%5Cdiv%205%20%3D%2011%5Cdiv%2012)
In any proportion, the product of the inner terms must be the same as the product of the outer terms:
![4\cdot 12 = 5\cdot 11 \iff 48=55](https://tex.z-dn.net/?f=4%5Ccdot%2012%20%3D%205%5Ccdot%2011%20%5Ciff%2048%3D55)
This is clearly false, and thus the two rectangles are not similar.
