Solve the equation by completing the square. If necessary, round to the nearest hundredth. x2+10x=18

answer: there are 453.592 grams in a pound.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%
