2n - 5 = 7
Add 5 to both sides.
-5 + 5 = 0
7 + 5 = 12
2n = 12
Divide both sides by 2.
2n / 2 = n
12 / 2 = 6
n = 6.
Your answer is 6.
I hope this helps!

Answer: choice B
Explanation: Go through each answer choice and try the Pythagorean theorem to see if it works. This is because a right triangle’s side lengths are described by the Pythagorean theorem. one side^2 + second side^2 = longest side^2. In a right triangle, this equation will be true. Let me show you what I mean
For answer choice A:
(root 2)^2 + (root 3)^2 = (root 4)^2
2 + 3 = 4
5 = 4
5 does not equal 4. Therefore it cannot be A.
For answer choice B:
(root 8)^2 + (3)^2 = (root 17)^2
8 + 9 = 17
17 = 17
this is true! therefore this is a right triangle and it’s B
Answer:
I assume c In the question is x
-3x + 7 = 1
-3x = - 6
3x = 6
X = 2
