Mathematics

Answer:

Step-by-step explanation:

If the roots are 7 and 3, then x = 7 and x = 3 are solutions. In factor form, x = 7 is (x - 7); in factor form, x = 3 is (x - 3). We FOIL these together to get

x^2-3x-7x+21 which simplifies to

x^2-10x+21 and we distribute in the 4:

4(x^2-10x+21) to get

4x^2-40x+84 which is another way to write the last choice you're given.

Emilie rides her bike x miles before she gets a flat tire. She walks 1/3mile to a bus stop and then takes a bus for 2 1/2miles.
ICE Princess25 [194]

Given :

Emilie rides her bike x miles before she gets a flat tire.

She walks 1/3 mile to a bus stop and then takes a bus for 2 1/2 miles.

To Find :

Which expression shows how many miles Emilie travels in all.

Solution :

We know, total distance covered is given by sum of all the distance she travelled.

Distance covered, D = x + 1/3 + 2 1/2

D = x + 1/3 + 5/2

D = (6x + 2 + 15)/6

D = (6x + 17)/6

Therefore, total distance travelled by Emilie is (6x + 17)/6 .
