Another submarine’s descent can be represented as, where y is the elevation and x is the time in hours. How long will it take this submarine to make the descent? I really need help.

Aline parallel to a triangle's side splits ab into lengths of x - 5 and x + 2. the other side, ac, is split into lengths of x and x + 12. what is the length of ac? a) 12 b) 24 c) 36 d)

What does x = in this equation x+3+2x=x+5

You’re giving a cube with a length of 2.5 cm and a width of 2.5 cm and a high of 2.5 cm you place it on a scale and it is 295 g calculate the density
