Aperson driving along the road moves rates of 56 miles per hour driven. how far does the person drive in 1.5 hours?

The person drives 84 miles in 1.5 hours.

Step-by-step explanation:

Since we have given that

Speed = 56 miles per hour

Number of hours = 1.5 hours

We need to find the "Distance covered":

As we know that

Distance = Speed × Time

Hence, The person drives 84 miles in 1.5 hours.

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,
