Perimeter of a rectangle can be represented by 2* length + 2 * width
We can represent the width with the variable x
We can represent the length by the expression 3x-1
So, now we can make a forumla and solve
2(3x-1) + 2(x) = 30
6x-2+2x = 30
8x = 32
x = 4 is the width of the rectange.
Now we find the length
3(4)-1
11 = Length
Mother is 36
and she is 6 year older than raju 3 times
N is rajiu age
N = 36÷ ( 6 x 3)
= 36 ÷ (18)
N = 2
Raju is 2 years old

Answer:
-1
Step-by-step explanation:
the additive inverse of -5is5 because (-5+5=0) &
the multiplicative inverse of -5is 1/-5. because (-5*1/-5=1)
therefore 5*1/-5=5/1*1/-5
=5/-5
=-1
Let x denote the length of the side of the garden which is covered fenced by a shed, and

be the width of the garden.
The perimeter of a rectangle is given by 2(length + width)
i.e.
which gives:

For the area to be maximum, the differentiation of A with respect to x must be equal to 0.
i.e.

Therefore, the maximum area of the garden enclosed is given by
