Step-by-step explanation:
examples of this property:
xy=yx
1*3=3*1=3
6*9=9*6=54
Answer:
32
Step-by-step explanation:
512/16=32
to get area you do LxW=A
so we just do the reverse
A/W=L
Answer:
you can't figure it out without the expression
Answer:
0, Infinite Solutions
Step-by-step explanation:
First we distribute 5 to 8x and -4
40x - 20 - 10 = 40x - 20 - 10
Next, collect like terms
40x - 30 = 40x - 30
This equation has infinite solutions because on both sides of the equation the values are the same.
Just to check
Add 40x to both sides
-30 = -30
Add 30 to both sides
Then we get 0
-- To create an even number:
2n is always even, no matter what 'n' is.
-- To test a number and see whether it's even:
'n' is even if (n/2) = (the greatest integer in n/2)
