Answer:
1. 3/2
2. 4
Step-by-step explanation:
hmmm a line with a slope of 0 is a horizontal one, and it has no slope-intercept form.
Check the picture below.
We know that
first garden dimensions -------> <span>6 feet long x 4 feet wide
second </span>garden dimensions-----> (6*2) feet long x (4*2) feet wide
then
second garden dimensions-----> (12) feet long x (8) feet wide
[perimeter first garden]=2*6+2*4---------> 20 ft
[perimeter second garden]=12*2+8*2---------> 40 ft
[the percent of change in perimeter]=[[perimeter second garden]-[perimeter first garden]}/[perimeter first garden]
[the percent of change in perimeter]=(40-20)/20-------> 1---------> 1*100-------> 100 %
the answer is 100%
