In my carpentry shop, i make three-legged stools and four-legged chairs. i look at my day's
work, and count 55 legs and 16 seats. how many stools and how many chairs did i complete
that day? type out your work, describing in words why you did each step and how you found
your answer.

if im not mistaking its

step-by-step explanation:  

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
