The first few steps in solving the quadratic equation 9x2 49x = 22 â’ 5x by completing the square are shown. 9x2 49x = 22 â’ 5x 9x2 54x = 22 9(x2 6x) = 22 Which is the best step to do next to solve the equation by completing the square? 9(x2 6x 3) = 25 9(x2 6x 3) = 49 9(x2 6x 9) = 31 9(x2 6x 9) = 103.

i just took the test, the correct answer is .. 31.5 in.

me

step-by-step explanation:

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
