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
To figure out 23.2%, first figure out how much 1% is by dividing 1500 divided by 100=15
Next, multiply the 15(1%) by the 23.2% to figure out how much that is.
23.2 x 15 = 348
Now, you have to add thr investment ($348) to his originsl amount of money ($1500).
$1500 + $348 = $1848
Zach now has $1848
Answer:
13 x 9 x 5
Step-by-step explanation:
because there is 13 steps in one flight and there fore we need to multiply 13 x 9
then we have to multiply the product by 5 because it is asked how many steps does she climb in five days
