Fill in the blanks between the numbers with correct math symbols 5_6_15_9=24

Step-by-step explanation:

To try to solve these problems, you could plug 'n play. If all the blanks are addition, you/ll be > 24

If all the blanks are subtraction, it will be < 0

Multiplication doesn't work for all of them.

I did notice that 15 + 9 = 24, 5*6 = 30, and you get back to 15 if you subtract 15 after multiplying 5 and 6

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.

we need the options
