3. two mathematicians are neighbors. each owns a separate rectangular plot of land that shares a boundary and has the
same dimensions. they agree that each has an area of 2x2 + 3x + 1 square units. one mathematician sells his plot to
the other. the other wants to put a fence around the perimeter of his new combined plot of land. how many linear
units of fencing does he need? write your answer as an expression in x.

Step-by-step explanation:

The factors of the given polynomial are (2x+1) and (x+1). We presume these are the side lengths of each rectangular plot. If the short side (x+1) was common, then the perimeter of the combined lot is ...

  4(2x+1) +2(x +1) = 10x +6 . . . units of fence for short side common

If the long side (2x+1) was common, then the perimeter of the combined lot is ...

  4(x+1) +2(2x+1) = 8x +6 . . . units of fence for long side common

step-by-step explanation:

ask goog great chance of finding the solution there

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
