15 × h
h= per hour
and to solve how many hours it would take:
600= 15 × h
600÷ 15 = 40
so it would take 40 hours to rise to the surface
Answer:
i think its the second one
Step-by-step explanation:
SQ<RS<QR
if its wrong am so sorry..
<span> zeros of the quadratic function when f(x) = 0
so
</span><span>8x^2 – 16x – 15 = 0
(8x + 5)(x - 3) = 0
8x + 5 = 0; x = -5/8
x - 3 = 0; x = 3
Answer
x = -5/8 and x = 3</span>
