Factor 4x2 + 24x + 36.

Answer:

\huge\boxed{\text{A) } 4(x+3)(x+3) }

Step-by-step explanation:

In order to factor this, we need to factor out a common term and then solve for x.

We can see that we can factor out a 4 from this entire equation as each term is a multiple of 4.

This leaves us with 4(x^2+ 6x + 9).

We can now solve for x for the expression in the parentheses, x^2 +6x + 9.

To solve for x, we can use the <u>XBOX</u> method. This tells us that:

  • When the two roots are added, they will equal b (in this case, 6)
  • When the two roots are multiplied, they will equal c (in this case 9)

Experimenting with some numbers gets us with 3 and 3 - 3+3 = 6 and 3*3 = 9.

Therefore, our roots will be (x+3)(x+3).

Putting that back into the factorization of our original expression, that leaves us with 4(x+3)(x+3).

Hope this helped!

Denise and Donna want to exchange secrets from across a crowded whispering gallery. Recall that a whispering gallery is a room w
Yuri [45]

Answer:

34 feet

Step-by-step explanation:

From the question, we are told that:

If the room is 30 feet high at the center and 90 feet wide at the floor,

Entire width of the room = 90 feet = 2a

a = 90/2 = 45

Height of the room = b = 30 feet

Foci (c)² = a² - b²

c = √a² - b²

c = √45² - 30²

c = √1125

c = 33.541019662 feet

Approximately to the nearest whole number = 34 feet

Denise and Donna should each stand 34 ft from the outer wall so that they will be positioned at the foci of the ellipse
