What pattern is represented by the polynomial ?
Ymorist [56]

Answer:

choice C. Perfect square trinomial is correct.

Step-by-step explanation:

We need to find the pattern which is represented by the polynomial 4x^2+12x+9.

To find that pattern, we need to factor 4x^2+12x+9

4x^2+12x+9

=4x^2+6x+6x+9

=2x(2x+3)+3(2x+3)

=(2x+3)(2x+3)

=(2x+3)^2

which is a perfect square.

Hence choice C. Perfect square trinomial is correct.

What does this equal y >4x - 5
Tresset [83]

Answer:

This represents the graph area above the line y = 4x - 5 shaded.

Step-by-step explanation:

y > 4x - 5 is an inequality.  First we graph y = 4x - 5, which has y-intercept (0, -5) and slope 4.  Next, we shade all of the area above this line (because the inequality y > 4x - 5 says that all y values are above 4x - 5).
