12 * 4
6 * 2 * 2 * 2
3 * 2 * 2 * 2 * 2
it should be 3 * 2^4...but that is not an answer choice
3 * 2^2 * 4 is ur answer....apparently they didn't factor the 4
Yes, if you solve both problems they come out to the same answer.
Let S be the first side.
Longest side is then 2S.
Third side is 2S-10.
Perimeter is sum of all three sides = S+2S+2S-10 = 75
=>
5S-10=75
5S=75+10=85
S=17
Therefore
S=17 is the first side.
Longest side is then 2S=2*17=34.
Third side is 2S-10=2*17-10=24.
The circumfrence of an 8ft circle is 8 x 3.14 = 25.12ft. Hope this helps!
