Use the information given below, to compare the cost of operating two different vehicles for one month (4 weeks).

You are considering two different cars. You drive to work, a 10 mile round trip, five days a week. Gasoline costs you $1.60 per gallon.
Car A gets 26 miles per gallon, would have $250 a year in maintenance costs, and would cost you $1,400 per year to insure.
Car B gets 18 miles per gallon, would have $500 a year in maintenance costs, and would cost you $1,000 per year to insure.

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.

answer: 10 turtles

step-by-step explanation: as turtles have four legs so 4.10=40 therefore birds are 4 which sue counted
