Answer:
Midpoint is (3.5, 2)
Step-by-step explanation:
the midpoint of the line segment whose endpoints are (5, 2) and (2, 2)
To find midpoint of two end points we use formula

(5, 2) , x1 = 5 and y1= 2
(2,2), x2=2 and y2= 2
Plug in all the values and find the midpoint using the formula


(3.5, 2)
So midpoint is (3.5,2)
Answer:
(2, -6)
Step-by-step explanation:
5n^2+20n-60
(5n+30)(n-2)
5n + 30 = 0
5n = -30
(5n = -30)/5
n = - 6
n - 2 = 0
n = 2
answer: (2, -6)
