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:
6x-5
Step-by-step explanation:
We apply distributive property to get rid of the first parenthesis, by multiplying each term inside by the factor 1/6:
now we get rid of the second parenthesis by multiplying the factor "
" times each of the terms inside the parenthesis (notice here that this factor is negative , so it will flip the signs of the terms it multiplies):
Next we combine like terms:
Answer:
d⁴y/dx⁴ = -12/x⁴
Step-by-step explanation:
y = 2In x
We want to find d⁴y/dx⁴. This is the fourth derivative.
Using product rule, first derivative is;
dy/dx = 2/x
Hello,
For the first question, congruent triangles have congruent corresponding angles and sides. For option choice A, MN corresponds with PQ, not PR, so it is incorrect to conclude that they are equal. The answer is A.
For the second question, we are given two angles and an not included side, so it would be AAS.
The answer is A, I believe.
Hope this helps!
