It is given by the sum of the money that the people has with the pending credits, and subtracted by the pending withdraws.

A walkway surrounds a rectangular garden. The width of the garden is 3 meters, and the length
rusak2 [61]

Answer:

You are given the width of the garden which is w= 8 feet

length of the garden which l= 6 feet

the width of the walkway is x

so for every side of the garden there is an x

so length overall would be 8+2x (length of garden + x one side + x other side)

and width overall would be 6 + 2x (width of garden + x of one side + x of other side)

area of rectangle is length*width

so the expression would be (8+2x)*(6+2x)

:))) smile....

I hope it is correct.

For the first one we divide every element by sqrt3

we get

q+2/sqrt3 =sqrt5/sqrt3

q=(sqrt5-2)/sqrt3

q=sqrt3*sqrt5-2*sqrt3/3

q=sqrt15-2sqrt3/3

which is the third option

For the second one

sqrt(2y-5) +4=8

first we move the 4 to the right

sqrt(2y-5)=4

we remove the square root by bringing to the power of two

2y-5=16

2y=21

y=21/2

y=10 1/2

third option
