To do these types of problems fast, I highly recommend you learn synthetic division-it helped me so much in Algebra II class.
It is kind of hard to explain on here, so I recommend searching synthetic division on you tube.
Anyway, by doing that you get (x-5) as a zero and are left with 6x^2 -x -1, which you can plug in the quadratic formula, and you get x= -1/3 and x=1/2

Hope, this tip helps you get started, but if not another tip would be (although it takes much more time) to just start dividing the polynomial by numbers like: x= (+/-) 6,1,2,3,5 because these numbers are factors of 5 or 6.

Serggg [28]

Answer:

plz give me BRAINLIEST answer

Step-by-step explanation:

For this case we observe that the time varies linearly with the obtained qualification.

The equation of the line can be obtained as follows

g-go = m (t-to)

where (go, to) are points that belong to the line.

To form the equation you need two points. These points are

(g1, t1) = (0,0)

(g2, t2) = (6.5.84)

Then, substituting, the equation of the line is

m = (84-0) / (6.5-0) = 84 / 6.5 = 12.923

g-0 = (12,923) * (t-0)

Rewriting.

g = 12.923t

The slope of the line is

m = 12,923

The Li family is going hiking. The distance from their car can be found using the function d(t) = 3t + 1, where d is the miles a

Sauron [17]

Answer:

Step-by-step explanation:

d(t)=3t+1 but d(t)=7

distance*time=3*time+1

so d(t)=7 is the same as

d(t)=3(2)+1

meaning that you hiked for 2 hours.

alright so I got the answer from here but I still can't figure out how we got 12p? can somebody explain step by step pls

Andreas93 [3]

There's no 12p in the simplification

$(2p+3)^{2} =(2p)^{2} +3^{2} = 4p^{2} +9$
