The GFC is 5.
Just divide all the numbers by 5 and if you're factoring, it should be easy.
Hope this helped.
Answer:
When we know all 3 sides, we use Heron's Formula
area = sqrt [s *(s-a) * (s-b) * (s-c)]
where "s" is the semi-perimeter which in this case equals
s = (6 + 8 + 12) / 2 = 13
area = sqrt [13 * 5 * 7 * 1]
area = sqrt 455
area = 21.3307290077
area = 21.33 square feet (rounded)

Answer:
1/2 mile
Step-by-step explanation:
3/8+1/8=4/8 or 1/2 simplified
1-1/2=1/2
same has to walk 1/2 mile more to walk his dog a full mile
An expression that represents the perimeter of the rectangle would be:
P = 2(3n+2) + 2(n-1)
