Answer:B
Step-by-step explanation:
Answer:
(y + 7i)(y - 7i)
Step-by-step explanation:
It cannot be factored using real numbers, but consider
7i × - 7i
= -49i² and i² = - 1
= 49
The factoring as a difference of squares to obtain
y² + 49 = (y + 7i)(y - 7i)
You se I’m so dum I can’t do this good lick
C because 19x899 equals 17081
Answer:
Probability = 0.23
Step-by-step explanation:
Probability of picking it choosen those at random without replacement =Pr(ace) + Pr(spade)+Pr(a four)
Probability = 4/52 + 4/52 + 4/52
Probability= 3(4/52)
Probability = 0.23
