The height, h (t), in feet, of a dolphin after it jumps above the water's surface at a given time, t, in seconds, can be modeled by h (t) = -2t + 12t. 15% 3D Which could be used to identify the time it will take the dolphin to reach its maximum height?

yeah i know the problem you need. i am taking it right now. the answer is step 3

~mickey

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
