What is the area of the rhombus shown below?

B

Step-by-step explanation:

The interior of the 4 triangles in the rhombus are right angle triangles. In addition AC is bisected by BD and BD is bisected by AC. Those form the sides of the right angle triangle.

So the sides of the right angle are

The area of one right angle is

The answer is B

B. 125.5 square units

Step-by-step explanation:

The area of a rhombus is half the product of the diagonals.

If the diagonals have lengths a and b, then the are is:

area = ab/2

area = (17)(15)/2

area = 255/2

area = 127.5

B. 125.5 square units

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
