10 x 7 = 70
1 x 7 = 7
9 x 7 = 70 - 7
9 x 7 = 63
(2x)2 > 3x2 is true the first two you can not have two x’s on the same side because where would you put them both when solving them the last one I’m not sure about
Answer:


Step-by-step explanation:
We know the definition of both functions:
, and 
A) In order to evaluate what
, let's first investigate what g(-1) is using the definition for this function:

Now let's find what f(2) is using f(x) definition: 
B) In order to evaluate what
, let's first investigate what f(3) is using the definition for this function:

Now let's find what g(7) is using the definition for this function:

Suppose the length of the triangle is x, if the perimeter of the rectangle is 100 ft, the width of the rectangle will be (50-x) ft.
Area of rectangle will be:
A=length*width
A=x(50-x)
A=50x-x^2
at maximum area, dA/dx=0
thus
dA/dx=50-2x=0
solving for x we get
2x=50
x=25
thus for maximum area length=25 ft
the size of the width will be
50-x=50-25=25 ft
thus the maximum area will be:
25*25=625 sq. feet
