Answer:

its 30 :/

Step-by-step explanation:

so we simplify

x(2x) = 1800

2[tex]x^{2}[/tex] = 1800

divide by 2 on both sides

[tex]x^{2}[/tex] = 900

find the square root of both sides

[tex]\sqrt x^{2} = \sqrt{900}[/tex]

x = 30

Answer:

30

Step-by-step explanation:

2(30) = 60

30 x 60 = 1800
