Answer:
60
Step-by-step explanation:
perimeter (p) = 8 + 17 + 15 = 40
semi-perimeter (s) = p/2 = 20
Area = square root of s(s-a)(s-b)(s-c) where a,b,c are the sides of the triange by Herons formula.
Therefore, area = 20(20-8)(20-15)(20-17) = square root of 3600 = 60
.5X+3.50y=33.50 Would be the equation hope this helps
Output = y
4 less = - 4 or y<
than the input = y < x by 4 or y + 4 = x
Happy to Help!
