The reciprocal of 7 is 1/7, reciprocal of 8 is 1/8, and reciprocal of 9 is 1/9
5/2
70 is the constant number that doesn’t change, but anytime you increase t you are raising it above 5/2. So every time you grow 5/2.
perimeter is 2L+2W
problem states width = 5L+13
so plug that in for w:
P=2L+2(5L+13)
now simplify
P=2L+10L+26
P=12L+26
66/128 * 100
51.56 % if rounding to the nearest hundredth.
51.6 % if rounding to the nearest tenth.
52 % if rounding to the nearest whole number.
