Well $16 times 16 would be $256.
If each shirt costs $1 then she could buy 16 shirts. 
        
                    
             
        
        
        
Obtuse, it does not fit Pythagoreans for a right triangle, two sides are not equal to be isosceles
        
             
        
        
        
<h2>
Step-by-step explanation:</h2>
A: f(x)=8x-2
1. Switch the f(x) to y
y=8x-2
2. Switch y to x and x to y
x=8y-2
3. Solve for y:
------------------------------
1. Add 2 to both sides.
  x=8y-2
+2     +2
2. Divide both sides by 8.
x+2=8y
---     ---
8       8
1/8x+1/4=y
3. Write in f-inverse form 
f^-1(x)=1/8x+1/4  
B: g(x)=2/3x+6
1. Switch the g(x) to y
y=2/3x+6
2. Switch y to x and x to y
x=2/3y+6
3. Solve for y:
------------------------------
1. Subtract 6 from both sides.
x=2/3y+6
-6        -6
2. Multiply both sides by 3/2 (to cancel out the 2/3)
x-6=2/3y 
2/3x-4=y
3. Write in f-inverse form 
g^1(x)=2/3x-4
C: h(x)-4x-12
1. Switch the h(x) to y
y=-4x-12
2. Switch y to x and x to y
x=-4y-12
3. Solve for y:
------------------------------
1. Add 12 to both sides.
x=-4y-12
+12    +12
2. Divide both sides by -4
x+12=-4y
------    ---
-4        -4
-1/4x-3=y
3. Write in h-inverse form
 h^2(x)=-1/4/x-3
 
        
        
        
He cannot make a rectangle with those measurements because the base of the rectangle need to be a least more that 1cm bigger than the height other wise its just a square
