Question

Guys i need help!!! The distributive property states that if a, b, and c are numbers or expressions, then a(b + c) = a • b + a • c.

6(5 + 6) = 6 • 5 + 6 • 6
6(5 + 6) = 30 + 36
6(5 + 6) = 66

Answer 1

Are you having trouble understanding the math?

let's look at
a(b + c) = a • b + a • c.

notice how they take the variable outside the parentheses (a)
and multiply it by the things inside the parentheses to get a*b, as well as a*c. finally, they add a*b + a*c.

this process is called the distributive property.

Answer 2

Ok*

Answer 3

The commutative property of addition says you can add numbers in any order and get the same answer. Is the same true for subtraction?

22 – 12
10 12 – 22
–10
10 ≠ –10
22 – 12 ≠ 12 – 22
a – b ≠ b – a
Changing the order in which you subtract numbers does change the result, so the commutative property does not work for subtraction.

Answer 4

so now let's apply it

6(5 + 6)

take what's outside the parentheses (6)
multiply it by the things inside the parentheses (6*5 and 6*6)
then add (6*5 + 6*6)
finally, simplify (30 + 36 = 66)

Answer 5

i got the other one i need help with this one ;-;

Answer 6

2 – 12 = 12 – 2
B.
(3 – 11) – 5 = 3 – (11 – 5)
C.
8 + 7 = 7 + 8
D.
(6 + 9) + 4 = 6 + (9 + 4)

Answer 7

Second post: like the post says, addition is commutative. this means you can change the order of the things being added.

so for 1 + 2, you can switch 1 and 2 and get the same result

1 + 2 = 3
2 + 1 = 3 also

Answer 8

However, with subtraction, you can't do this.

1 - 2 = -1
2 - 1 = 1
which are not the same

For the problem you posted, what exactly is being asked? I didn't quite catch the question.

Answer 9

lemme make another one
