The answer is (m+5) (m+7).
3( x+ 3(4x-5))
3x + 9(4x-5)
3x + 36x - 45
39x - 45 is equivalent to 3( x+ 3(4x-5))
Answer:

Step-by-step explanation:
Using the product to sum formula
sinxcosy =
[ sin(x + y) + sin(x - y) ] , then
2sinxcosy = sin(x + y) + sin(x - y)
Given
2sin75°cos15° ← with x = 75 and y = 15 , then
= sin(75 + 15) + sin(75 - 15)
= sin90° + sin60°
= 1 + 
= 
We can actually see that the statements that are true are:
A. x = 1 is a solution.
C. x = –1 is a solution.
<h3>What is rational equation?</h3>
Rational equation is actually known as an equation that contains at least one fraction. The denominator and numerator are known to be polynomials.
We can see then that:

It's clear that: x ≠ 0 and x ≠ -6.
Looking for the LCM of the left hand side, we will have:

So, we will see that left hand side and right hand side are equal.





or

So, we can see that options A and C are correct.
