When adding negative and positive numbers, you can use the associative and commutative properties to group all of the positive addends and then group all the negative addends. which expression shows the second step of this method?

5 + (-1) + (-5) + (-2) + 11 + (-7) + 2

The second step of this method is

The value of the given expression is

Step-by-step explanation:

Given expression is

To find the value of the given expression  :

Arranging positive and negative addends  by using the associative and commutative properties of the given expression as below:

The second step of this method is

The value of the given expression is

true

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
