Answer:
Length of rectangle: 2n - (1/3) + 9/(3n)
Width of rectangle = 3n
Rectangle area = A = 6 n^2 - n + 9
Step-by-step explanation:
Rectangle area = A = 6 n^2 - n + 9
test what the roots are: b^2 - 4ac = (-1)^2 - 4*6*9 < 0 no real roots
-215 < 0 discriminant
(6 n^2 - n + 9) / (3n) =
2n - (1/3) + 9/(3n)
If the area is divided by 3n, the quotient is 2n - (1/3) and the remainder is 9

Answer:
-6x+12
-9+5a
7x+63
8y-4/5x-12
Step-by-step explanation:
To solve these all you have to do is take the number outside of the parenthesis and multiply them by each term.
-3(2x)-3(-4) All I did here was expand the problem to show what i mean by terms.
-6x+12
Do this for each problem.
0.1(-90)+0.1(50a)
-9+5a
-7(-x)-7(-9) For this one you are taking negatives times negatives so each answer will be positive.
7x+63
4/5(10y)+4/5(-x)+4/5(-15)
8y-4/5x-12
Can you type the answers in plz. I can't see the pic
Answer:
x= -8
Step-by-step explanation:
2x+3x-12=8x+12
5x-12=8x+12
5x-8x=12+12
-3x=24
24/-3
x= -8
