Suppose the width of the path is x.
the dimensions of the extended rectangle are (12+x+x), and (16+x+x)
(12+2x)(16+2x)=285
4x²+56x+192=285
4x²+56x-93=0
Not easy to factor it, so use the quadratic formula to solve:
x={-56+√[(56²-4*4*(-93)]}/2*4 or x={-56-√[(56²-4*4*(-93)]}/2*4
x=1.5 (ignore the negative solution.)
Answer:
its the first one ma'am
Step-by-step explanation:
6 tens and 2 ones can be written as 62
5/2=40/16. You can try to cross multiply by 2 times 40 and dividing by 16 to get 5.
I think the answer is a that’s my opinion
