Answer:
7 ft
Step-by-step explanation:
Perimeter of a rectangle is denoted by the formula: 
, where l is the length and w is the width.
We know that P = 20 and that w = 3. So, let's plug these values in:
Isolate the variable 
by subtracting 6 from both sides and dividing by 2:
Thus, the answer is 7 feet.

Step-by-step explanation:
Whatever number is in the interval, for instance, g(-4), is the x value on the graph. From then on, located the value on the graph and go either up or down (depending on the line) in order to get your answer.
The correct given equation is:
v = [3 (h + 1)^2.5 + 580 h – 3] / 10 h
So to solve for the instantaneous velocity at t = 1, we
must set h = 0. However we cannot do that since h is in denominator and a
number divided by a denominator is infinite. Therefore we must set h to
something almost zero. In this case, h = 0.0000001, so that:
at t = 1
v = [3 (0.0000001 + 1)^2.5 + 580 (0.0000001) – 3] / 10 *
0.0000001

Answer:
<em>the unit rate is 0.8x per unit y</em>
<em></em>
Step-by-step explanation:
the proportional relationship is y = 
this means that the constant of proportionality k = 
= 0.8
re-writing, we have
<em>y = 0.8x</em>
<em>therefore, the unit rate is 0.8x per unit y</em>
