Answer:
y - intercept = 4
Step-by-step explanation:
I'm not completely sure but I believe this should be right.
Say the width is W and the length is L
L=3W (and of course W=W)
Now you use the perimeter formula P=2L+2W
80=2(3W) + 2W)
80=6W+2W
80=8W Divide both sides by 8
W=10
Now that you know the width, substitute it back into L=3W to find the length
L=3(10)
L=30
The dimensions are length: 30 cm and width: 10 cm
x+4
___________
(x+2)|(x^2+6x+9)
-x^2-2x
__________
4x+9
-4x-8
__________
1
so the quotient is:
(x+2)(x+4)+1/(x+2)
X=10
First, remove the parentheses so it could turn into 150-2x-90=4x (the plus sign gets turned into a minus sign because of a certain rule.
Then do 150-90 which will result in 60-2x=4x.
Then subtract -4x on both sides. This will leave you with 60-6x=0.
Next, subtract 60 in both sides. This will leave you with -6x=-60.
Finally, divide by -6 on both sides. This will leave you with the answer x=10.
