The area of rectangular is A= length x width
120 feet of fancing = ---------------------------------- (the above line)
!-----------------------------------------!
! !
x ! the enclosed area ! x
! !
!---------------------------------------- !
120 -(x+x)
so the area is A = (120-2x) (x)= 120x-2x²
First divide both sides by 2 so that we can get rid of the parentheses, so we get
now subtract 5 from both sides
then finally we want x alone so we'll divide both sides by 3 and get our final answer!
Answer:
The GCF for the variable part is
k
Step-by-step explanation:
Since
18
k
,
15
k

contain both numbers and variables, there are two steps to find the GCF (HCF). Find GCF for the numeric part then find GCF for the variable part.

Answer:
The first one is the answer.
Step-by-step explanation:
It's an arithmetic sequence. It has a common difference.
d = an - a_n-1
an = -12x + 12
a_n-1 = - 7x + 8
d = -12x + 12 - (-7x + 8)
d = -12x + 12 + 7x - 8
d = -5x + 4
Try it. Let's try for the third term
-12x + 12 - 5x + 4
- 17x + 15 which is exactly what the third term is.
The answer is 4.77 euro.
First I found out what the cost of one pen was.
I did: 6.36/12 pens
The answer was: 0.53
Then I did 0.53 times 9
And I got the answer.
Can you please tell me how to add a picture to a question though?
