The answer to the question
Answer:
42 and 41
Step-by-step explanation:
So how I did it tbh I went everywere with this but I went backwards because the how you find the mean of something is adding all the values and then dividing them by the number of values(40+41+42+45+45+48+54=315, 315divided by 7=45) but anyway 45x7(because multiplication is the opposite of division)that equals 315-232 which is the answer to 40+45+48+54+45 which were the numbers that were given
5x^2 -2x +1 = 0
D = 4 -20 = -16
so this mean that the quadratic has no real solutions
18 that's the answer:)<span />
