4x²-12x+9=5
4x²-12x+4=0
x= 12±√(144-4*4*4) / 2*4
x= 12 ± √(144-64) / 8
x=12±√80. /. 8
x= 12+4√5. /8
x=3±√5 / 2. C and E
The first x coordinate is given by 0 and the second one is given as j. So the length of the base is j. (Sometimes in math they give letters rather than numbers. And since you know it is an isosceles then the other vertex should be at x-coordinate half j or j/2.
Answer:
The answer to this question is not 36/25 but 6 1/10.
Step-by-step explanation:
Probability a gets a head = 1/2
.. .. .. b .. .. ... .. = P(a gets tail) * 1/2 = 1/2 * 1/2 = 1/4
.. ... . .. c .. .. .. .. . = P(and and b gets tail) * 1/2 = 1/4 * 1/2 = 1/8
Answer:
The answer is X=-4 hope this helps.
