Answer: A.
Explanation: Because to persuade someone you are trying to convince them to do something through reasoning or argument.
Let
x-------------> amount added <span>to each side
</span>A-------------> area increased----------> 84 ft²
we know that
A=(10+x)*(5+x)=84-----------> 10*5+10*x+5*x+x²
50+15x+x²=84----------> x²+15x-34=0
<span>solving the second order equation
</span>x1=-17
x2=2
the answer is x=2 ft
The slope of the line between the points On the line would be -1. And the y intercept would be 1.
Y = -x + 1.
