The product of two numbers is 450. the first number is half the second number. which equation can be used to find x, the greater number? = 450 225x2 = 0 x2 = 450 450x2 = 0

X*y = 450

y = 1/2x

x (1/2x) = 450

1/2x^2 = 450

x^2 = 450 * 2

x^2 = 900

x = sqrt 900

x = 30

y = 1/2 (30)

y = 15

so ur numbers are : x = 30 and y = 15 ... but I am not sure of ur answer choices.
