Answer:

Sum of -8a³b+3a²b²-5,2+5a²b² and 3a³b+7-9a²b² is:

-5a³b-a²b²+4

Step-by-step explanation:

We have to find the sum of:

-8a³b+3a²b²-5,2+5a²b² and 3a³b+7-9a²b²

-8a³b+3a²b²-5+2+5a²b²+3a³b+7-9a²b²

= -5a³b-a²b²+4

Hence, sum of -8a³b+3a²b²-5,2+5a²b² and 3a³b+7-9a²b² is:

-5a³b-a²b²+4

-8a^3 b + 3a^2 b^2 - 5 + 2 + 5a^2 b^2 + 3a^3 b + 7 - 9a^2 b^2
= -5a^3 b - a^2 b^2 + 4

answer is

C.) -5a3b - a2b2 + 4

Select the postulate or theorem that you can use to conclude that the triangles are similar.

ioda

Answer: SSS Similarity Theorem

Step-by-step explanation:

SSS Similarity Theorem says that the lengths of the corresponding sides of two triangles are proportional, then the triangles must be similar.

In the given picture , we have two triangles XYZ and KMN, where

$\dfrac{3}{4.5}=\dfrac{4}{6}=\dfrac{2}{3}$

$\Rightarrow\ \dfrac{XZ}{KN}=\dfrac{ZY}{MN}=\dfrac{XY}{KM}=\dfrac{2}{3}$

By SSS similarity theorem , we have

ΔXYZ ≅ ΔKMN
