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.

yes because When you are given an equation and a specific value for x, there should only be one corresponding y-value for that x-value. For example, y = x + 1 is a function because y will always be one greater than x. Equations with exponents can also be functions.

Step-by-step explanation:

The notation y = f(x) defines a function named f. This is read as “ y is a function of x.” The letter x represents the input value, or independent variable. The letter y, or f(x), represents the output value, or dependent variable.
