9. a car moving at a constant speed passes a timing
device at t= 0. after 8 seconds, the car has
traveled 840 feet. what linear function in the
form y= mx + b represents the distance in feet,
d, the car has traveled any number of seconds, t,
after passing the timing device?

b.

step-by-step explanation:

i just know

answer: our required factorization will be

(3x+4)(x²-5)

step-by-step explanation:

since we have given that

now, we will write it as :

so, we get

5(3x+4)

similarly,

here, we get,

2(3x+4)

together it becomes,

hence, our required factorization will be

(3x+4)(x²-5)
