A square has sides with lengths of (x - 2) units. A rectangle has a length of x units and a width of
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

Which statement describes the effect on the parabola y = x2 - 1 when it is changed to y = x2 +6?
zlopas [31]

Initial:

y=x^2-1

Changed to:

y=x^2+6

As you can see the change is: from -1 to +6.

In a equation as follow:

y=x^2+k

The k is a transformation that moves up or down the graph of the function. If k is changed to a less value the graph moves down, If k is changed to a greather number the graph moves up.

In this case the graph moves up

To find the number of units the graph moves find the difference betwwen values of k:

6-(-1)=7

Then, the parabola y=x²-1 is moved 7 units up when it is changed to y=x²+6
