11. No
12. 85
13. 5 square root of 2
14.
Answer:
Step-by-step explanation:
Any pair of dimensions that total 16 will give a rectangle with a perimeter of 32.
P = 2(L +W)
32 = 2(L +W)
16 = L +W . . . . . . . divide by 2
__
This is true for L = 13 and W = 3. It is also true for L = 10 and W = 6, or any other pair of dimensions x and (16-x).
10.
50+(2x)=20+(5x)
-20 -20
-2x -2x
30=3x
divide both sides by 3
10=x
