Answer:
if the area is 7 then the total side length is sqrt 7. 2 is also sqrt 4 so x pretty much equals sqrt 3. this equation is a typo, as sqrt isn't a solution. moreover if you factor the square, it will equal x squared plus 4x plus 4.
Answer:
24
Step-by-step explanation:
We want the ratios to be equal
18:x 9:12
18 9
--------- = -----------
x 12
We divide by 2 to get from 18 to 9
x ÷2 =12
Multiply each side by 2
x ÷2*2 =12*2
x = 24
18:24 9:12
