Answer:
<h3>The expression for the perimeter P is
feet.</h3><h3> Area=49=lx square feet ( here
)</h3>
Step-by-step explanation:
Given that rectangle with height equals 4times width.
It can be written as
Let x be the width of the given rectangle
Therefore 
Rewritting the above equation we get
<h3>To write an expression for the perimeter P of the given rectangle :</h3>
Also given that area of the rectangle is 49 square feet.
Area=49 square feet.
We know area of rectangle = lw square units.
<h3>Therefore area=49=lx square feet ( here area=49 and w=
)</h3>
Rewritting we get
lx=49 square feet.
<h3>
feet</h3><h3>Perimeter P
units </h3>
<h3>
feet.</h3>
3x2+8x-10 // the answer is 8x
x= 1.68596491
So just round that number and you have your answer.
Answer:
F(X) > 0 over the interval (-infinity, -4)
Step-by-step explanation:
F(x) is the function and really can be written like y. As you can see from the graph, between -4 and -infinity the graph is constantly increasing and will never decrease below zero again, therefore D (the 4th statement) is the correct one.
