Answer:
9
Step-by-step explanation:
So we want to solve like if it was just a basic equation. We start with 25+3.50x<17+7.50x and get rid of our smallest x. That means we get rid of the 3.50x by subtracting from both sides and our new equation is 25<17+4x. Let’s get our x by itself shall we, so let’s subtract 17 from both sides and we get 8<4x. Finally all we do is divide by 4 and just like that 2
The answer is 19.6 cm^2
you should find the height of the triangle by heron formula: it will be 9.8
so the area is

good luck
