I really need a picture to answer this question.
The midpoint of the coordinate passing through (2, 4) and (2, -7) is 
<h3>The midpoint of a line</h3>
The formula for calculating the midpoint of a line is expressed as:

Given the coordinate points (2, 4) and (2, -7). Substituting this values

Hence the midpoint of the coordinate passing through (2, 4) and (2, -7) is

Answer:
0
Step-by-step explanation:
6-24n=3n+6
Add 24n to both sides of the equation:
6=27n+6
Subtract 6 from both sides:
27n=0
Therefore, n=0.
Hope this helps!
Answer:
(a - 6)²
(3c + 1)²
30e(e - 1)²
Step-by-step explanation:
a^2-12a+36
a² - 6a - 6a + 36
a(a - 6) - 6(a - 6)
(a - 6)(a - 6)
(a - 6)²
9c^2 + 6c + 1
9c² + 3c + 3c + 1
3c(3c + 1) + 1(3c + 1)
(3c + 1)(3c + 1)
(3c + 1)²
30e^3 - 60e^2 + 30e
30e(e² - 2e + 1)
30e(e² - e - e + 1)
30e[e(e - 1) - (e - 1)]
30e(e - 1)(e - 1)
30e(e - 1)²
