Write an equation and show your work: There were five different Foil Kites that each descend 50 feet per second for 5 seconds. Find the total change in altitude for all 5 kites.

Change in altitude = (50 x 5) feet

The total change in altitude for all 5 kites. = 250 feet

Step-by-step explanation:

Given : Rate of descent = 50 feet per second  (speed)

Time = 5 seconds

Since, distance = speed x time

Change in altitude = Rate of descent x Time

Change in altitude = 50 x 5 feet  [required equation]

= 250 feet

Hence, the total change in altitude for all 5 kites. = 250 feet

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,
