Step-by-step explanation:

The answer has to be in feet units

Now that we know the height is 5 cm equivalent to 150 feet, what is the width of the building in feet units

5 cm = 150 ft

Which of the equations are true identities? a. (3x-2y)(2y-3x)=9x^2-4y^2 b. (2k+5r)(2k-5r)=4k^2-25r^2
krok68 [10]

Answer:

b.(2k+5r)(2k-5r)

Step-by-step explanation:

We have to find the equation which are true identity.

a.(3-2y)(2y-3x)

(3x-2y)(2y-3x)=3x(2y-3x)-2y(2y-3x)

=6xy-9x^2-4y^2+6xy

(3-2y)(2y-3x)\neq 9x^2-4y^2

b.(2k+5r)(2k-5r)

(2k)^2-(5r)^2

Using identity

(a+b)(a-b)=a^2-b^2

4k^2-25r^2

It is true.

Hence, option b is true.
