Simplyfy 12(2+7+1 please some one help io

120

Step-by-step explanation:

I’m assuming you ment 12(2+7+1)

s

2+7=9

9+1=10

so here’s it is now

12(10)

when there’s 2 numbers like that you multiply

so 12 x 10 = 120

and there’s your answer

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
