Answer:
if we were to put this together, it would be <em>3i+1 </em>or <em>1+3i</em>. <em>i</em> would be the variable,<em>3</em> the coefficient.
Step-by-step explanation:
We know that perimeter of the triangle its a+b+c=570
Moreover we know that:
a=b
b=b
c=2b-30
Finally we can substitute into our formula
b+b+2b-30=570
4b-30=570 /+30
4b=600 /:4
b=150 - its a and b side
c=2*b-30
c=300-30
c=270 - its c side
I think the person with the fewer points scored 54 points
