Which of the following is an example of the additive identity?
a +(-a) = 0
a+0=0
a+0= a

a+0= a

Step-by-step explanation:

we know that

The additive identity property says that if you add a real number to zero or add zero to a real number, then you get the same real number back

so

Let

a > a real number

a+0=0+a=a

therefore

a+0= a

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..
