Answer:
Option A m(3m + 4)(3m - 4)
Step-by-step explanation:
we have
Factor m
![m[9m^{2}-16]](https://tex.z-dn.net/?f=m%5B9m%5E%7B2%7D-16%5D)
Apply difference of squares
we know that
![[9m^{2}-16]=(3m+4)(3m-4)](https://tex.z-dn.net/?f=%5B9m%5E%7B2%7D-16%5D%3D%283m%2B4%29%283m-4%29)
substitute
![m[9m^{2}-16]=m(3m+4)(3m-4)](https://tex.z-dn.net/?f=m%5B9m%5E%7B2%7D-16%5D%3Dm%283m%2B4%29%283m-4%29)
Answer:
The correct option is;
d) CPCTC
Step-by-step explanation:
The phrase Corresponding Parts of Congruent Triangles are Congruent with the acronym CPCTC, is used as valid reasoning in the provision of a proof, after the existence of congruency between two triangles has been proven
Given that the triangles ΔDOG and ΔCAT have been proven congruent, we have that the corresponding vertices are;
Vertex D corresponds to vertex C
Vertex O corresponds to vertex A
Vertex G corresponds to vertex T
Therefore, given that ΔDOG ≅ ΔCAT, we have;
∠D ≅ ∠C by CPCTC
∠O ≅ ∠A by CPCTC
∠G ≅ ∠T by CPCTC.
LCM I believe. Because it’s every 6 days he does both
