Answer:

(12 $x^{4}$ -15x³ + 18x²)

Step-by-step explanation:

We have to simplify the given expression -3x² (5x - 4x² - 6) By distributive property.

-3x² (5x - 4x² - 6) = (-3x²) (5x) - (-3x²) (4x²) -6 (-3x²)

= -15x³ + 12 $x^{4}$ + 18x²

= (12 $x^{4}$ -15x³ + 18x²)

Therefore, simplified form of the given expression is (12 $x^{4}$ -15x³ + 18x²)

If f(x) is the height, in cm, of a sunflower plant that is x days old, which of the following statements best describes the mean

mario62 [17]

Answer:

Step-by-step explanation:

We are given f(x) is height in cm while x is days old.

We are also given f(60)=210.

If you compare f(60) to f(x) you should see that x is 60 so we have the sunflower is 60 days old. Since f(60)=210, then you have the height of the sunflower is 210 cm tall.
