A= 1/2 and c = 9. what does 2ac equal?
also if s = 32 and t = 45, what does st equal?
whoever answers correctly (check yourself! ) will be marked brainliest

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

first one because it can't have a fraction in it
