Answer:
-23.18, -0.82
Step-by-step explanation:
- h² + 24h + 19 = 0
- h²+2h*12+12²-125=0
- (h+12)²-√125²=0
- (h+12+11.18)(h+12-11.18)=0
- (h+23.18)(h+0.82)=0
- h+23.18=0 ⇒ h= -23.18
- h+0.82=0 ⇒ h= -0.82
Step-by-step explanation:
In my opinion Option A is the correct answer because
Product of 3 and x = 3x
7.5 more than that = 3x + 7.5
The points you are looking for are the midpoints of segments JL and JK.
J(-2, -1), K(4, -5), L(0, -5)
The midpoint of segment JL is
(-2 + 0)/2, (-1 + (-5))/2) = (-2/2, -6/2) = (-1, -3)
The midpoint of segment JK is
(-2 + 4)/2, (-1 + (-5))/2) = (2/2, -6/2) = (1, -3)
Answer: The coordinates are (-1, -3), (1, -3)
