A new office building in town has x2 + 4 floors. Each floor is 3x2 – 5 feet high. Which expression shows the total height of thi
Jlenok [28]

Answer: OPTION B.

Step-by-step explanation:

You know that:

  • x^{2}+4 represents the number of floors of the  new office building in town.

  • 3x^{2}-5 represents  the height of each floor in feet.

Therefore, you must multiply x^{2}+4 by 3x^{2}-5 to obtain the expression that shows the total height  in feet of this office building.

Then:

(x^{2}+4)(3x^{2}-5)=3x^4-5x^2+12x^2-20

Add the like terms:

=3x^4+7x^2-20

Therefore, the answer is the option B.
