Not sure what algebra tiles are
not sure how to absolutely prove
I can prove it works at least most of the time by subsitute ing number for x
remember that 0,1,2 have special properties and are not very good for subsituting so
try 4
4+8(4)=4(2(4)+1)
true or false?
4+8(4)=4(2(4)+1)
multipily
4+32=4(8+1)
36=4(9)
36=36
this is treu at least for the number 4
another way is to believe in the distributive property where
a(b+c)=ab+ac so then
4(2x+1)=4(2x)+4(1)=8x+4=4+8x
Answer:
Step-by-step explanation:
20,24,25,27,31,35,38
minimum;20
medium: 27
maximum: 38
lower quartile: 24
upper quartile:35
put numbers in number order
the first number is the minimum, the last number is the maximum. the middle number "split" is the median.
quartiles are the numbers in the middle of the data you just "split"
(so like a quarter)
i may be wrong i haven't done this in years
3.2-5.7=-2.5 so its have to be a negative because a smaller number subtract a bigger number have to be equal to a negative number.
