Identify the area of the rhombus. the answer with the red arrow is incorrect!

Step-by-step explanation:

Look at the picture.

The formula of an area of a rhombus:

d₁, d₂ - diagonals

We have d₁ = 30 cm.

Use the Pythagorean theorem to calculate d₂ = 2x.

            subtract 225 from both sides

d₂ = (2)(8) = 16 cm.

Substitute:

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
