It would be D because when you divide fractions, you multiply by the reciprocal of the fractions so 2/5 * 10/9. Then you simplify and get 4/9. Hope this helps!!!!!!!

Use the method of completing the square to transform the quadratic equation into the equation form (x – p)2 = q. x2 - 12x - 9 =
marissa [1.9K]

Hence, the correct answer is: C) (x - 6)^2 = 45

Further explanation:

Given equation is:

x^2-12x-9=0

We will move the constant term on other side of the equation

x^2-12x=9

To complete the square, we will take the coefficient of x and divide it by 2, as we already know that one term is x.

\frac{12}{2}=6

So, adding (6)^2 on both sides

(x)^2-2.x.6+(6)^2=9+(6)^2\\(x-6)^2=9+36\\(x-6)^2=45

Hence, the correct answer is: C) (x - 6)^2 = 45

A prism with a triangular base has a volume of 432 cubic feet. The height of the prism is 8
Rashid [163]

Answer:

9 feet

Step-by-step explanation:

Given:

A prism with a triangular base has a volume of 432 cubic feet.

The height of the prism is 8.

The triangle base has a base of 12 feet.

Question asked:

The height of the triangular base of the prism = ?

solution:

Volume of  triangular prism = Area of triangle \times height

432 = Area of triangle \times8

Dividing both side by 8

54 = Area of triangle

54 =  \frac{1}{2} \times base \times height

54 = \frac{1}{2} \times12\times height\\54 = \frac{12}{2} \times height

Multiplying both side by 2

108 = 12 \times height

Dividing both side by 12

9 = height

Thus, height of the triangular base of the prism is 9
