Monday through friday ms. carter ran a total of 25.5 miles. lf she ran the same number of miles all 5 days, how many miles did she run in one day

Divide total miles by total days:

25.5 miles / 5 days = 5.1 miles per day.

5.1 miles

Step-by-step explanation:

Divide the total number of miles by the number of days.

25.5 miles ÷ 5 days = 5.1 miles / day

Ms. Carter ran 5.1 miles in one day.

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.

the answer will be b x² +x-1
