Which property is used to simplify the expression 1+(6+0)=1+6? a. additive inverse property. b. additive idenity property. c. associative property of addition. d. commutative property of addition

The answer is B. Additive Identity Property.

In short, the additive identity property states that if you add zero to any number the sum would equal that number. In this case, when 0 is added to 6, the sum is still 6.

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
