Fill in the blank with a number to make the expression a perfect square. x^(2)-8x + ?

So, 16 should be added to the expression to make it a complete square.

Formula used : (a-b)²=a²-2ab+b²

the answer is 15% decrease

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
