vagabundo [1.1K]

Answer:

(A)The area of the square is greater than the area of the rectangle.

(C)The value of x must be greater than 4

(E)The area of the rectangle is (x^2-4x) \:Square \:Units

Step-by-step explanation:

The Square has side lengths of (x - 2) units.

Area of the Square

(x-2)^2=(x-2)(x-2)=x^2-2x-2x+4\\=(x^2-4x+4) \:Square \:Units

The rectangle has a length of x units and a width of  (x - 4) units.

Area of the Rectangle =x(x-4)=(x^2-4x) \:Square \:Units

<u>The following statements are true:</u>

(A)The area of the square is greater than the area of the rectangle.

This is because the area of the square is an addition of 4 to the area of the rectangle.

(C)The value of x must be greater than 4

If x is less than or equal to 4, the area of the rectangle will be negative or zero.

(E)The area of the rectangle is (x^2-4x) \:Square \:Units

Conan O'Brien hosts the Conan show and Andy Richter, his sidekick, writes for it. Conan needs 4 hours to rehearse and host a goo
andrew-mc [135]

Answer:

C

Step-by-step explanation:

1. Conan needs 4 hours to rehearse and host a good show.  Andy needs 10 hours to do the same. So, Cohan needs 6 hours less than Andy to  rehearse and host a good show. This means Cohan has an absolute advantage in the production of show hosting.

2. Conan writes one usable joke in an hour,  Andy needs 2 hours to do the same. So, Cohan has an absolute advantage in the production of joke writing.

Thus, Cohan has an absolute advantage in the production of both show hosting and joke writing.

Correct option is option C.
