Answer: -D=3/2

Explanation:
If a positive D is equal to -3/2 you would just have to multiply both side by a negative 1: D(-1)=-3/2(-1). After multiplying that you would get -D=3/2 because a negative time a negative is equal to a positive.

2+ (-3)^2 - (-1)<br><br> please explain! :3
Ugo [173]

Answer:

12

Step-by-step explanation:

Hello!

First of all you have to understand the order of operations.

PEMDAS

Parenthesis, Exponent, Multiplication/Divison, Addition, Subtraction.

From this you can see that we first have to deal with the exponent, then multiplication, then the addition.

So we get 2+9-(-1)

The 9 is from -3^2

2+9+1

11+1

12.

Hope this helps!
