X²-10x+25=0 quadratic equation by factoring

lisov135 [29]

Answer:

x = 5

Step-by-step explanation:

${x}^{2} - 10x + 25 = 0 \\ {x}^{2} - 5x - 5x + 25 = 0 \\ x(x - 5) - 5(x - 5) = 0 \\ (x - 5)(x - 5) = 0 \\ ( x- 5) = 0 \: or \: (x - 5) = 0 \\ x = 5 \: or \: x = 5 \\ x = 5$

A simplified model of the human blood-type system has four blood types: A, B, AB, and O. There are two antigens, anti-A and anti

dexar [7]

Answer: Blood type will be A when event "A" happened and event "B" did not happen. Blood type will be B when event "A" did not happened and event "B" happened. Blood type will be AB when both events happened and blood type will be O when both events did not happen.

Step-by-step explanation:

S={AntiA reacts; AntiA does not react; AntiB reacts; AntiB does not react}

If AntiA reacts and AntiB reacts = AB (A∩B)

If AntiA does not react and AntiB does not react= O (A'∩B')

If AntiA reacts and AntiB does not react= A (A∩B')

If AntiA does not react and AntiB reacts= B (A'∩B)
