Jamie rode her bike home for 5 blocks before realizing she forgot her math book at school and would need it for her homework. she rode back to school, found her math book, and then rode home.

which graph best represents the scenario described?

The second graph  best represents the scenario described.

Step-by-step explanation:

Given: Jamie rode her bike home for 5 blocks before realizing she forgot her math book at school and would need it for her homework.

We can see in the second graph that the starting point of her ride is at 9 blocks.

Then the graph goes down to 4 blocks by difference of  5 blocks in 5 minutes, where she realized that she forgot her math book at school.

Then the graph goes up by 5 blocks , where she reached her school back at 9 blocks in 9 minutes.

Then she took 3 minutes rest (time taken to get the book from the school) an d then the graph goes down to 0 blocks. {i.e she reached her home by 17 minutes}

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
