What are the the numbers?
Change the 1/5 to 4/20 and the 3/4 to 15/20 and then add them together
Hello,
Assume x the side of the square.
(x+7)²=4x²
==> ((x+7)-2x)((x+7)+2x)=0
==> (-x+7)(3x+7)=0
==> x=7 or x=-7/3 (to exclude since side must be positive)
Proof:
(7+7)²=196
4*49=196
More than likely they refer to the maximum or minimum value of a function on some open interval. For example the function $f(x)=x^2$ has a minimum value of 0 and it occurs at x=0.
