Answer:
The missing value is 5/2
Step-by-step explanation:
Points A and C are the endpoints of one diagonal. Its slope will be
.. (5-(-1))/(-1-(-5)) = 6/4 = 3/2
Points B and D are the endpoints of the other diagonal. Its slope will be
.. (-2-6)/(3-(-9)) = -8/12 = -2/3
The diagonals cross at right angles, so the figure is a rhombus or a kite.
The midpoints of the diagonals are
.. (A +C)/2 = (-5-1, -1+5)/2 = (-3, 2)
.. (B +D)/2 = (-9+3, 6-2)/2 = (-3, 2)
The midpoints of the diagonals are the same. The diagonals are perpendicular bisectors of each other, so the figure is a rhombus.
Answer:
8s+8
Step-by-step explanation:
Put it into groups: (4s+4s)+(10-2)=8s+8

Represent 24 as a sum of two numbers, first number from first die and second number from second die.
24=19+5=18+6=17+7=16+8=14+10=13+11=12+12=11+13=10+14=9+15=8+16=7+17=6+18=5+19=4+20 (the sums 15+9 and 20+4 are absent, because there aren't numbers: 20 on the first die and number 9 on the second die). Totally, you receive 15 different representations of 24.

(here
means that you have 20 possibilities to roll first number or blank face on the first die and 20 possibilities to roll number or blank face on the second die).
