Determine whether 4x2 + 6x + 9 is a perfect square. if so, factor it. if not, explain why. a. no, 4x2 + 6x + 9 is not a perfect square. 4x2 and 9 are perfect squares, but 6x is not equal to 2(2x)(3). so 4x2 + 6x + 9 is not a perfect square. b. yes, 4x2 + 6x + 9 is a perfect square. (2x + 3)2 c. yes, 4x2 + 6x + 9 is a perfect square. (2x − 3)2 d. no, 4x2 + 6x + 9 is not a perfect square. 4x2 and 9 are perfect squares, but 6x is not a perfect square. so 4x2 + 6x + 9 is not a perfect square.

  A.  No, 4x² + 6x + 9 is not a perfect square. 4x² and 9 are perfect squares, but 6x is not equal to 2(2x)(3).

Step-by-step explanation:

The square of a binomial is ...

  (a +b)² = a² +2ab +b²

Here the first and last terms are perfect squares, so we might assume that ...

  a = 2x, b = 3

This would require the middle term to be 2ab = (2)(2x)(3) = 12x, which it is not. So, the given trinomial is not a perfect square.

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic

11) obtuse

13)right

15) acute
