Step-by-step explanation:
Step-by-step explanation:
For quadratic equation ax^2 + bx + c = 0 to have two distinct real roots,
b^2 - 4ac must be positive.
b^2 - 4ac > 0
(k - 3)^2 - 4(3 - 2k) > 0
k^2 - 6k + 9 - 12 + 8k > 0
k^2 + 2k - 3 > 0
Answer:
x=12, DO=45O, G=45, DG=90
Step-by-step explanation:
Mid point means both lenghts are equal
4x-3=2x+21
2x=24
X=12
-----------------
1)4(12)-3=48-3=45
2)2(12)+21=24+21=45
-----------------------------
DO=45
OG=45
DG=90
Answer: I think around 0.70
Step-by-step explanation:
