Extra points to brainiest !
a quadratic equation is written in four equivalent forms below.
i. y = x(x - 6) + 8
ii. y = (x - 3)^2 - 1
iii. y = x^2 - 6x + 8
iv. y = (x - 2)(x - 4)
which of the forms shown above would be the most useful if attempting to find the x-intercepts of the quadratic equation?

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.

step-by-step explanation:

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.

cool? what is the actuall ?

step-by-step explanation:

the graph line crosses the x axis at both -6 and -2, so the answer would be the second one.
