Answer: 5 hours
Step-by-step explanation: c=35•h+25
25=40•h-35•h; 25=5•h
well let's round. 90= 100, 75=80 that is how I face it. now 80 is 1/5 of 5/5= 100. so as a (%) we would sort it like:::: it is 80% out of +100 so he must have grown around 13%-16% due to him being 75kg in the past.
Its 2x^2-4x, to check it add it to 3x^2-2x or
2x^(2)-4x+3x^(2)-2x
Assuming that the given shape is a cuboid,
volume=l×w×h
v=s³ (since cuboids have same length, they have same side length)
62=s³
∛62=s
s=3.957 ≈ 4 units
Hope I helped :)
