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.

A train leaves Philadelphia at 2:00 PM. A second train leaves the same city in the same direction at 4:00 PM. The second train t
polet [3.4K]

Answer: First train speed shall be 42 mi/hr

Second train speed shall be 84 mi/hr

Yes it is the valid answer, it gets annoying when almost everyone enters the wrong answer for a good laugh. Either way, hope this helps! Have a spectacular day.

Step-by-step explanation:

What is the 1st train's head start in miles?

Let +s+ = the speed of the 1st train in mi/hr

From 2PM to 4PM is 2 hrs

+d%5B1%5D+=+s%2A2+

---------------------

Let +d+ = distance the 2nd train travels until

it overtakes the 1st train

From 4PM to 6PM is 2 hrs

Start time when the 2nd train leaves

---------------------

Equation for 1st train:

(1) +d+-+2s+=+s%2A2+

Equation for 2nd train:

(2) +d+=+%28+s%2B42+%29%2A2+

--------------------

Substitute (2) into (1)

(1) +%28+s%2B42+%29%2A2+-+2s+=+s%2A2+

(1) +2s+%2B+84+-+2s+=+2s+

(1) +2s+=+84+

(1) +s+=+42+

and

+s%2B+42+=+42+%2B+42+

+s+%2B+42+=+84+

------------------

The 1st train's speed is 42 mi/hr

The 2nd train's speed is 84 mi/hr

---------------------------

check:

(2) +d+=+%28+s%2B42+%29%2A2+

(2) +d+=84%2A2+

(2) +d+=+168+

and

(1) +d+-+2s+=+s%2A2+

(1) +d+-+2%2A42+=+42%2A2+

(1) +d+=+84+%2B+84+

(1) +d+=+168+

Which of the following are rational numbers {7,-5,2/3,5.79,,√13,√-4}
Ilia_Sergeevich [38]

Answer:

7, -5, 2/3, 5.79

Step-by-step explanation:

rational numbers are numbers you can put in fraction form. \sqrt{13} is not a perfect square, therefore you cannot put it in fraction form. \sqrt{-4} is an imaginary number. Rational numbers are in the Real Numbers category, so it is not a rational number.
