Step-by-step explanation:
First write it out:
6048/72=L
This is because the formula for Area is Width * Length.
Then divide the area bu the width to get your answer:

Rounding it to the tens place so your answer for 12mm is going to be 10
Answer:
x = - 9 (negative 9)
Step-by-step explanation:
The x intercept is where y = 0. When y = 0, the point is on the x axis.
So use the equation and replace y with 0.
-2x + 1/2y = 18
-2x + 1/2(0) = 18
-2x + 0 = 18
-2x = 18
x = - 9
Check you answer by putting your answer for x into the equation. See if it does make y = 0
-2x + 1/2y = 18
-2(- 9) + 1/2y = 18
18 + 1/2y = 18
1/2y = 0 so y must also equal 0
