Answer:
Option B
Step-by-step explanation:
I did the test and I got it right.
The identity property of addition states that the sum of any number and 0 is the original number.
so...x + 0 = x would be the identity property of addition (also called the additive identity)
I think the answer is 20.25 because when solving for the area of a triangle you do 1/2 base times height and so the equation would be
1/2(9)(4.5)
you would start by doing 9(4.5) which equals 40.5
then you would divide by 1/2 which equals 20.25
hope this helps:)
12(3w+8)=25
36w+96=25 ( I used the distributive property)
-96 . -96
36w=-71
w=-1.972222.... ( I divided both sides by 36)
