vesna_86 [32]

Answer:12 m

Step-by-step explanation:

Given

Width of garden $W=8\ m$

Total fencing $T=40\ m$

If Lulu has enough fencing to go around her rectangular garden then , it should be equal to perimeter of garden

Suppose L is the length of garden

Therefore perimeter is $P=2(L+W)$

$2(L+W)=40$

$L+W=20$

$L=20-8=12\ m$

thus length of fencing is $12\ m$

Answer:

Option C

Step-by-step explanation:

Assuming P represents the number of outcomes, n the number of competitors and r the number of places to be awarded....

$P = n! / ( n - r )!\\P = 8! / ( 8 - 3 )!\\P = 8! / 5!\\\\Algebra, P = 336 \\Solution = Option C$

There are 336 different possible ways for the winners to be chosen.
