4x^2 -2x +3
mark me as brainliest if i’m right !
Expand (x+2)^2: x^2 + 4x + 4 : remember that (a+b)^2 = a^2 + 2ab + b^2
So: x^2 + 4x + 4 - x^2 = 60
Answer:
Step-by-step explanation:
Givens
Lake Eyre (Austrialia) = 15 meters below sea level = - 15
Pensacola (Florida) = + 12 metes above sea level
Solution
Distance between = Pensacola - Lake Eyre
Distance between = 12 - - 15
Distance between = 27
Answer
27 meters.
(3,12)(5,20)
rate of change (slope) = (y2 - y1) / (x2 - x1)
slope = (20 - 12) / (5 - 3)
slope = 8/2 = 4 credits per course
63$
five hours = 45$
1 hour = 9$
7 hours = 63$
