Select the polynomial that is a perfect square trinomial.
alexdok [17]

Answer:

Option D. It's a perfect square trinomial.

Step-by-step explanation:

(a) 36x² - 4x + 16

= (6x)² - 2(2x) + (4)²

It's not a perfect square trinomial

(b) 16x² - 8x + 36

= (4x)² - 2x(4x) + (6)²

It's not a perfect square trinomial

(c) 25x² + 9x + 4

= (5x)² + 2(\frac{9}{2}x) + (2)²

It's not a perfect square trinomial

(d) 4x² + 20x + 25

= (2x)² + 2(10x) + (5)²

= (2x+5)²

It's a perfect square trinomial.

pshichka [43]
The formula for this is: (sale price) / (1 - percentage)
Percentage have to be in decimal form, so divide percentage by 100 to get the decimal form.

220/(1-.20) = $275

The original price was $275.

The ratio of 1 3/4 to 2 1/2 is equal to the ratio of 14<br> to what number?
Lynna [10]

Answer:

x = 20

Step-by-step explanation:

Write and solve an equation of ratios, as follows:

  1 3/4         14

------------ = --------

  2 1/2           x

where x is the unknown number.

Converting the mixed numbers to improper fractions, we get:

7/4       14

------ = -----

5/2        x

Here there are two numerators and two denominators.  Multiplying all four quantities by 4 will remove some of the fractions:

 7        56

------ = -------

 10       4x

Cross multiplying, we get:

28 x = 560, or x = 20
