Answer:
C −2a^3+9a^2+45a+6ab^2+18b^2
Step-by-step explanation:
(a+3) ( −2a^2+15a+6b^2)
Distribute the a to the large term in parentheses and the 3 to the large term in parentheses
a ( −2a^2+15a+6b^2)+3 ( −2a^2+15a+6b^2)
−2a^3+15a^2+6ab^2 −6a^2+45a+18b^2
Combine like terms
−2a^3+15a^2−6a^2+6ab^2 +45a+18b^2
-2 a^3 + 9 a^2 + 6 a b^2 + 45 a + 18 b^2

Step-by-step explanation:
Answer:
JKM is acute and MKL is obtuse
Step-by-step explanation:
because an acute triangle's interior angles are always 180° and an obtuse triangle's sum is greater than 90°
Answer:
Devon use 
instead of 
in his reason. So, we can say that triangles are not similar.
Step-by-step explanation:
If two triangles are similar then their corresponding sides are proportional.
If triangle TUV and XYZ are similar, then
The reason given be Devon is
He use the correct concept, that the corresponding sides of similar triangle are proportional. But he use instead of in his reason.
Therefore his reason is incorrect. So, we can say that triangles are not similar.
