Answer:

86.4

10x +56 = 180

10x = 180 - 56

x = 12.4

180 - 4*12.4 + 44 =86.4

What number should be added to both sides of the equation to complete the square? x2 + 8x = 4

GuDViN [60]

The number that should be added to both sides is 16 because its half of b, which is then squared. You then get (x+4)^2=20, which you then square root both sides and get x+4=+-20 and then subtract the 4 to get x=-4+-20
