Junior e aline tem 100 livros . se tirarem 25 livros de junior e derem a aline , ele ficara com o mesmo número de livros . quantos livros tem cada um ?

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

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

i believe it’s 165 because if u add 137 and 58 u get 195 and then subtract that from 360 and there’s ur answer

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3
