10 points! Please help me Thanks! <3 :Elle wants to attend the Art Institute of Dallas, which costs about $12,000 per year. She has $2,500 saved and received a grant for $4,000. How much does she need to cover the remaining cost?

5,500

Step-by-step explanation:

added 2,500 and 4,000 that equals 6,500 the remaining amoumt is 5500

$4,500

Step-by-step explanation:

You basically add the 2 thousand five hundred and the 4 thousand and then the result of the two you then take it away from the 12 thousand.

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: i think it's a
