Answer:
n = -4/5
Step-by-step explanation:
-3/4 n + 1/8 n= 1/2
use the rules of signs for multiplication
-3/4 n + 1/8 n= 1/2
multiply both sides 8
-6n + n = 4
collect like terms
-5n = 4
divide both sides by -5
n=-4/5
or alternative form
n=-0.8

Answer: 70!
Step-by-step explanation: set the equation equal to eachother. x=30, plug it in
The area of the plot is 600 (20x30) and it needs to be 1200 (600x2)
only the width is changed so you divide it by the length which is 30
1200 divided 30 is 40 so the answer is 40 (another way is to just multiply the width by 2 since it's the only thing changing)
hope this helps :)
