There are
4

swimmers in a race. there will be a first-place and a second-place prize awarded. in how many different ways can the
2

prizes be awarded?

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

its line 2 i just added the rest or else it wouldn't let me answer
