perimeter=(L+W)2

L=x^2+2x-3

W=2x^2+3x+5

(x^2+2x-3+2x^2+3x+5)2

(x^2+2x^2+2x+3x-3+5)2

Scientists are studying the temperature on a distant planet. They find that the surface temperature at one location is 40° Celsi

jok3333 [9.3K]

Answer:

T(h) = 20 - 3h

Step-by-step explanation:

We are told that for every km you go up, the temp goes down 3°.

Let's say you go up 1km, then the temp should be 17°. We can easily represent it by the equation: T(h) = 20 - 3h

If we go up 1km: T(1) = 20 - 3*(1) = 20 - 3 = 17°

If we go up 2km: T(2) = 20 - 3*(2) = 20 - 6 = 14°

If we go up 3km: T(3) = 20 - 3*(3) = 20 - 9 = 11°
