Answer:
k = 4
Step-by-step explanation:
In order for the claim to be true, (x-3) must be a factor of each of the terms in the first expression. That is, you must have that expression factor as ...
(x -3)(2x +5) +(x -3)(x +7)
Factoring out (x -3), we get ...
= (x -3)(2x +5 +x +7) = (x -3)(3x +12)
= 3(x -3)(x +4)
The value of k must be 4.
First, you can distribute the -2 to 1 - 7n
the new equation is 5n + 34 = -2 + 14n
then, you can add 2 to both sides to cancel the -2 on the right
now you have 5n + 36 = 14n
after this, you add -5n to both sides, again, to cancel the 5n on the left
you are left with 34 = 9n
lastly, divide both sides by 9 to find the value of n, which is 4.
