Answer:

The root of the polynomial equation x(x-2)(x+3)=18 is x=3

Step-by-step explanation:

x(x-2)(x+3)=18

Dividing both sides of the equation by x:

x(x-2)(x+3)/x=18/x

(x-2)(x+3)=18/x

We can use this system of equations:

(1) y=(x-2)(x+3)

(2) y=18/x

And using a graphing calculator we get:

x=3, y=6 → Point=(x,y)=(3,6)

Answer: The root of the polynomial equation x(x-2)(x+3)=18 is x=3

Malia is planting tomato and pepper plants in her garden each tomato plant t requires 6 square feet and each pepper plant p requ
MAVERICK [17]

Answer:

6 t + 4  p   ≤  150   is the required inequality.

Step-by-step explanation:

Here, the area required for 1 tomato plant = 6 sq ft

So, the area required to plant t tomato plants  

= t x ( Area required by 1  tomato plant)   = t x ( 6 sq ft)  = 6 t

the area required for 1 pepper plant = 4 sq ft

So, the area required to plant p  pepper plants  

= p x ( Area required by 1  pepper plant)   = p x ( 4 sq ft)  = 4 p

Now, total area of the garden = 150 Sq ft.

Also, area of p pepper pants + t tomato plants =   (6 t +  4 p) sq ft

So, now according to the question:

Total area of both plants ≤ Total area of the garden

⇒ (6 t +  4 p) sq ft   ≤  150 sq ft

or, 6 t + 4  p   ≤  150   is the required inequality.
