Write the equation in standard form. Then identify the values of a, b, and c that you would use to solve the equation using the Quadratic Formula. *Hint: the value of a needs to be positive. 4x+8=5x^2

1.7266

-0.9266

Step-by-step explanation:

5x²= 4x+8

5x²-4x-8=0

here, a= 5, b= -4 and c=-8

x= (-b + √(b²-4ac))/2a

= (4 + √ (16+160))/10

= (4 + 4√11)/10

either, x= 1.7266

or, x= -0.9266

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 %
