A black widow spider laid 346 eggs. A wolf spider laid
107 eggs.
How many more eggs did the
black widow spider lay than the
wolf spider?

239 eggs

Step-by-step explanation:

We know that a black widow spider laid 346 eggs while a wolf spider laid 107 eggs and we are asked to find how much more eggs were laid by the black widow than the wolf spider.

To solve this, we need to subtract the amount that was laid from the black widow to the amount the wolf laid.

346 - 107

239

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.
